To find Length or Breadth when Area of a Rectangle is given

Let’s discuss how to find length or breadth when area of a rectangle is given.

When we need to find length of a rectangle we need to divide area by breadth.

Length of a rectangle = Area ÷ breadth

ℓ = A ÷ b

Similarly, when we need to find breadth of a rectangle we need to divide area by length.

Breadth of a rectangle = Area ÷ length

b = A ÷ ℓ

Formulas:

To find Length or Breadth when Area of a Rectangle is given


For Example:

1. Find the length of a rectangle whose breadth is 5 cm and area is 90 sq. cm.

Solution:

Breadth (b) = 5 cm,

Area (A) = 90 sq. cm.

Length (ℓ) = Area ÷ breadth

= 90 ÷ 5

= 18

Therefore, length of rectangle = 18 cm.



2. Find the breadth of a rectangle whose length is 200 cm and area is 10 m2.

Solution:

Length (l) = 200 cm,

Area (A) = 10 m2

100 cm = 1 m.

Length (ℓ) = Area ÷ breadth

Length (ℓ) = 200/100 m = 2 m.

Breadth (b) = A ÷ ℓ

= 10 ÷ 2 m.

= 5 m.

Therefore, breadth of rectangle = 5 m.
