If the cost of painting is $8.50 per square feet, then find the total cost of painting for the wall. The length and width of a rectangular shaped wall are 8 ft and 12 ft respectively.
So, the perimeter of the rectangle is 6 square cm. Therefore, the width of the rectangle is 2 cm. In the figure shown above, consider the right triangle ABC. In the figure shown above, length is given, that is 3 cm. To find the area of a rectangle, we have to know its length and width. Have a look.The figure shown above is a rectangle with 3 cm length and the measure of one the diagonals is √13 cm. 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.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 lengths.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:
