Question

The area of a room is $\frac{21}{4}$ square meters. If its width is 14 meters, what will its length be?

• A. $\frac{3}{8}m$
• B. $\frac{7}{8}m$
• C. $\frac{5}{8}m$
• D. $\frac{3}{10}m$

Answer 1

The correct option is A $\frac{3}{8}m$

Area of the room = length $\times$ width

$\Rightarrow \frac{21}{4}=\text{length}\times 14$

Dividing, both sides by 14

$\Rightarrow \frac{21}{4\times 14}=\text{length}$

$\Rightarrow \text{Length}=\frac{3}{4\times 2}=\frac{3}{8}m$

The length of the room will be $\frac{3}{8}m$
