Question

The area of a rectangle is equal to 240 square centimetres. What is the length of the rectangle if its breadth is 12 cms

• A. 20 cms
• B. 12 cms
• C. 10 cms
• D. 16 cms

Answer 1

The correct option is

B

20 cms

Let the length of the rectangle = “l” cms

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

Forming an equation:

Hence $240=\text{l}\times 12$

$\Rightarrow \frac{240}{12}=l$

$\therefore l=20\text{cm}$
