Question

The area of a rectangular piece of a board is $36c{m}^2$. If the width is $4cm$ of the length, what is the width of the board?

• A. $9cm$
• B. $12cm$
• C. $4cm$
• D. $26cm$

Answer 1

The correct option is A

$9cm$

Given,

Area of a rectangle = $36c{m}^2$

Width of rectangle = $4cm$

Area of a rectangle = $length\times breadth$

$\therefore 36$ = $4\times breadth$

$\Rightarrow \frac{36}{4}=breadth$

$\Rightarrow breadth=9cm$
