Question

A rectangle has a length 30 cm and breadth 25 cm. A square region of side 5 cm is cut out from it. Find the area of the remaining portion.

• A. 750 $c{m}^2$
• B. 725 $c{m}^2$
• C. 700 $c{m}^2$
• D. 650 $c{m}^2$

Answer 1

The correct option is B 725 $c{m}^2$

$\text{Area of rectangle}=30\times 25=750c{m}^2$

Side of square cut out = 5 cm
$\text{Area of square}=5\times 5=25c{m}^2$

$\text{Area of the remaining portion}=750c{m}^2-25c{m}^2$
$=725c{m}^2$
