## How do you find L and W from perimeter?

Substitute the value of width in the formula of the perimeter of a rectangle and simplify the value of length ‘l’, that is, P = 2 (l + A/I). l = 4 units (or) 2 units. Substitute the value of the length ‘l’ of the rectangle in the equation w = A/l and simplify to find the width ‘w’.

### How do you find L and W from area?

The formula for the area, ‘A’ of a rectangle whose length and width are ‘l’ and ‘w’ respectively is the product of length and width, that is, “A = l × w”.

**What are the characteristics of a rectangle?**

A rectangle is characterized by length (L) and width (W). Both length and width are different in size. In the figure above, a rectangle ABCD has four sides as AB, BC, CD, and DA and right angles A, B, C, and D.

## How do you find the length and width of a rectangle?

where a a and b b are the length and width of the rectangle, respectively. Length of Diagonal of Rectangle Formula: The diagonal of a rectangle is determined by the following formula d = √a2 + b2 d = a 2 + b 2 where a a and b b are the length and width of the rectangle, respectively.

### What is the formula of the area of a rectangle?

It is measured in square units. Therefore, the area of the rectangle is the area covered by its outer boundaries. It is equal to the product of length and width. The formula of area of rectangle is: \\(A = Length \imes Width \\;\\; unit^{2}\\) Diagonal of a Rectangle. A rectangle has two diagonals, that bisects each other.

#### What are the sides of a rectangle called?

For example, if one side of a rectangle is 20 cm, then the side opposite to it is also 20 cm. A rectangle is characterized by length (L) and width (W). Both length and width are different in size. In the figure above, a rectangle ABCD has four sides as AB, BC, CD, and DA and right angles A, B, C, and D.
