How to Find the Area of a Rectangle

To calculate the Area Of Rectangle, you should multiply the length by the width. The Formula to calculate the Rectangle area is given here;

Area Of Rectangle = Length * Width

A= S 2 or A= S.S

Where A is the area, s is the length of a side, and · means multiply.
A = L * W where A is the area, L is the length, W is the width, and * means multiply.

A square is a rectangle with 4 equal sides. To find the area of a square, multiply the length of one side by itself.

Examples to Calculate the Area Of Rectangle

Example 1: Find the area of a square with each side measuring 2 inches.

Solution: A= S.S

A= (2 in) (2 in) = 4 in 2

Example 2: A rectangle has a length of 8 centimeters and a width of 3 centimeters. Find the area.

Solution: A = L * W

A= (8cm) (3cm) = 24 cm 2

Example 3: The area of a square is 9 square centimeters. How long is one side?

Solution: A= S.S

9cm 2 = s * s

Since 3 · 3 = 9, we get 3 cm · 3 cm = 9 cm 2 so s must equal 3 cm.

Example 4: The area of a rectangle is 12 square inches and the width is 3 inches. What is the length?

Solution: A = L * W

12 in 2 = L * 3in

Since 4 · 3 = 12, we get (4 in) · (3 in) = 12 in 2. So L must equal 4 in.

L = 4 in

Example 5: What is the area of this rectangle?

Solution: The formula is:

Area = w × h

w = width

h = height

We know w = 5 and h = 3, so:

Area = 5 × 3 = 15
