Therefore, perimeter of the rectangle = 2 (length breadth) units We know that the area of the rectangle is given byĪrea = length × breadth A = a × b square units ⇒ a = \(\frac\)Ī wire in the shape of rectangle of length 25 cm and breadth 17 cm is Have a look.Therefore, perimeter of the rectangle ABCD If you're interested in pixel density, try our PPI calculator.īlackboards, mirrors, frames, canvas, sheets of paper, notebooks, envelopes, money, flags, rectangle pools. Screens of electronic devices - tablets, smartphones, TVs – use this area of a rectangle calculator or our dedicated screen size tool to estimate how much space on the wall your screen will take up – or how big the screen of the phone you want to buy is. Rectangle tablecloths – given the size of your table, you can find out what tablecloth is needed or how much lace or hemming tape you need to use.ĭoors or window glass – did a storm or a golf ball break your window pane? Calculate the area and estimate the repair cost, given the price of a sq ft or sq meter. Of course, you won't find an ideal rectangle in reality, as it always has a third dimension but if it's small compared to the other two measurements, the approximation is good enough. That's why our rectangle calculator may be useful not only for math classes but also in your everyday life problems. Surprisingly, we are surrounded by rectangular objects. Your body is well proportioned and athletic in appearance.Ĭheck out also our body fat calculator, made to help you estimate the percentage of body fat in your total body weight. Then you'll get the information about what your body shape is.įor example, the rectangle body shape is defined as a "boyish" body type – your hips, waist, and bust are about the same size. If you are wondering which shape your figure resembles, check out our body shape calculator.Īll you need to do is to measure your bust, waist, hips, and high hip and type the values into the tool. Or not?īody shape type is one of the most searched for problems connected to rectangles. You could think that the world would be easier to draw if every country were a rectangle. Also, in a circle calculator, you'll find a dedicated paragraph about the roundness of the countries with a similar table and examples. If you're interested in the topic, you can have a look at this explanation and discussion of the results. How is it even possible to be rectangular and round at the same time?! As you can guess, it's all about the definition of rectangularity and roundness, which may not be adequate for complex or scattered shapes – and the borders of countries are usually such examples, containing sharp edges, small islands, or colonies somewhere on the other part of the globe. The confusing thing is that the 2nd most rectangular country – Vatican – is at the same time the 4th-roundest country, and Poland, 5th in roundness classification, is 9th in the rectangularity ranking. The USA is in the middle of the ranking, mainly because of the eccentricity of Alaska and Hawaii. You can think of your own properties as well, e.g., concerning the revolution of a rectangle – along the side or diagonal to get a cylinder or a cone, respectively.Įgypt is the leader, but that shouldn't surprise anybody checking the shape of that country on the map. The sides of the shape are parallel to the diagonals. Lines joining the midpoints of the sides of a rectangle form a rhombus, which is half the area of the rectangle.In a rectangle with different side lengths (simply speaking – not a square), it's not possible to draw the incircle.The intersection of the diagonals is the circumcenter – a circle exists which has a center at that point, and it passes through the four corners.Other lesser-known rectangular properties: Opposite sides of a rectangle are parallel to each other and have equal length.You can find the diagonal length using the Pythagorean theorem. Two diagonals, which bisect each other.Two lines of reflectional symmetry – vertical and horizontal through the center.Rectilinear – its sides meet at right angles.Equiangular – all its corner angles are equal to 90 degrees.Cyclic – meaning that all corners lie on a single circle.Rectangles have many interesting properties:
