![]() The diagonal can be calculated using the Pythagorean theorem. To get the perimeter the sum of a and b is multiplied by 2 (because the opposite sides are identical). The area of a rectangle can easily be calculated by multiplying the length of side a and b. In these situations the tool will just show one of the two possible solutions. For example, a rectangle with perimeter 10 and area 6 has the sides 2 and 3, but it is unclear if it is a that is 2 and b that is 3 or if it's the other way around. If neither of them are specified there can often be multiple solutions. ![]() As the size of the rectangle changes, the area is recalculated. Try this Drag the orange dots to move and resize the rectangle. The tool therefore uses the more neutral naming, a and b. The number of square units it takes to completely fill a rectangle. When calculating a rectangle's diagonal, perimeter and area it does not matter which side is the base and which side is the height. The distance between the vertical sides are often called the base, while the distance between the horizontal sides are called the height. Rectangles are often depicted with the longest sides horizontally and the shorter sides vertically. The word rectangle comes from the Latin word rectangulus, a combination of rectus (right) and angulus (angle), which refers to the rectangle's four right angles (90°). By that calculation, it would take nearly 12 square meters to. If all the sides of a rectangle have the same length it's usually called a square instead. or M2, is a unit of area measurement equal to a square measuring one meter on each side. Have a look.A rectangle is a geometric shape with four sides where all angles are 90°. Screens of electronic devices – tablets, smartphones, TVs – use this area of a rectangle calculator 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.īlackboards, mirrors, frames, canvas, sheets of paper, notebooks, envelopes, money, flags, rectangle pools. 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 per 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. 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. All you need to do is to measure your bust, waist, hips, and high hip and type the values into the tool. 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.īody shape type is one of the most searched-for problems connected to rectangles. 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. ![]()
