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

Answer 1

The correct option is C

9 cm

Given,

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

Width of rectangle = $4cm$

Area of a rectangle = $length\times breadth$

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

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

$\Rightarrow breadth=9cm$
