Question

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

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

Answer 1

The correct option is D

9 cm

Given:
Breadth of a rectangle = 7 cm
Area of the rectangle = 63 $c{m}^2$

Area of rectangle = Length $\times$ Breadth
$\Rightarrow$ Length = $\frac{Area}{Breadth}$
$\Rightarrow$ Length = $\frac{63c{m}^2}{7cm}=9cm$
