How to Find the Area of a Rectangle

Calculating the area of a rectangle

The area of a rectangle is the area covered by a rectangle in two-dimensional space. To calculate the area of a rectangle, you should first know what a rectangle is, how it is defined, and how to multiply the length and width of a rectangle. Unlike a square, a rectangle has two length and width sides. Besides length, you should also measure the width, which is called the breadth.

First, you must understand how area is measured in terms of square meters. You must convert the value of the area if the value is outside of square meters. Then, you must multiply the converted value by the area in square meters. This formula is not valid for irregular shapes, such as a trapezoid, but works for squares and rectangles.

Another method of calculating the area of a rectangle is by measuring the area of a square or rectangle drawn on a scaled grid. If you know the length and width of a rectangle, you can multiply the squares in the shape by the number of squares on the grid.

Using the Pythagoras’ theorem

The area of a rectangle can be calculated using the Pythagoras’ Theorem. This formula states that the square of the hypotenuse of a rectangle equals the sum of the squares of the other two sides. If a rectangle has right angles, the area of the triangle is equal to the area of the right angles.

An example of this proof is shown in the lower figure. The area of the left green side is the same as the left portion of the bottom parallelogram. The area of the two other green parallelograms is the same as the sum of their areas. By applying this equation, you can find the area of any rectangle.

The Pythagoras’ Theorem can also be used to find the area of a triangle. A right triangle has two right angles. The right angle is opposite the side that is thirteen units long.

Using the area of a square calculator

Using the area of a square calculator is a useful tool when you need to know the area of a certain shape. Usually, you have to know the length and width of a square to calculate the area of a rectangle. But, you may need to know the diagonals as well, so using an area of a square calculator is helpful for this purpose.

A rectangle is a shape with two sides of equal length and width. It has four right angles, and the opposite sides are parallel. A simple online calculator will let you find out the area of a rectangle by multiplying the length and width.

The area of a rectangle is defined as the total area covered by a flat surface. The area is equal to the length times the width. Therefore, if a square has a length of 10 cm, its area is equal to 100 square units.
