Question

The area of a rectangle is 96 cm². If the breadth of the rectangle is 8 cm, find its length and perimeter

• A. Length = 12 cm; Perimeter = 40 cm
• B. Length = 19 cm; Perimeter = 50 cm
• C. Length = 14 cm; Perimeter = 45 cm
• D. Length = 25 cm; Perimeter = 90 cm

Answer 1

The correct option is A Length = 12 cm; Perimeter = 40 cm

Length of rectangle =$\frac{\text{Area}}{\text{breadth}}$
=$\frac{96{\text{cm}}^2}{8\text{cm}}=12\text{cm}$
Perimeter =$2(12+8)$
$=2\times 20$
$=40\text{cm}$
