Question

The area of a rectangle is equal to 480 square centimetres. What is the length of the rectangle if its breadth is 12 cms

• A. 20
• B. 30
• C. 50
• D. 40

Answer 1

The correct option is D

40

Let the length of the rectangle = “l” cms

Area of a rectangle $=\text{length}\times \text{breadth}$

Forming an equation:

$480=\text{l}\times 12$

$l=\frac{480}{12}$

$l=40\text{cms}$
