Question

The length of a rectangle of area 10 $c{m}^2$ is 5cm. Its breadth will be:

• A. 4cm
• B. 2cm
• C. 5cm
• D. 1cm

Answer 1

The correct option is B 2cm

Area of a rectangle = Length $\times$ Breadth
Given: Area = 10 $c{m}^2$
Length = 5 cm

$\Rightarrow$ 10 $c{m}^2$ = Length $\times$ breadth
$\Rightarrow$ 10 $c{m}^2$ = 5 $\times$ Breadth
$\Rightarrow$ Breadth = 10 $c{m}^2$ $÷$ 5 cm = 2 cm
