Question

If the area of a rectangle is 63 $c{m}^2$ and its breadth is 7 cm, then find its length.

• A. 6 cm
• B. 7 cm
• C. 8 cm
• D. 9 cm

Answer 1

The correct option is D

9 cm

Given:

The breadth of a rectangle = 7 cm
Area of the rectangle = 63 $c{m}^2$

Area of a rectangle = length $\times$ breadth
63 $c{m}^2$ = length $\times$ 7 cm
$\text{length}=\frac{Area}{breadth}$
$=\frac{63c{m}^2}{7cm}$
$=9cm$
