Question

The area of a rectangle is 96 𝑐𝑚2 . If the breadth of the rectangle is 8 𝑐𝑚, find its perimeter. [1] 20 𝑐𝑚 [2] 48 𝑐𝑚 [3] 32 𝑐𝑚 [4] 40 𝑐�

Answer 1

Area of rectangle = L×B

96 = L×8

L = 96/8

Length of rectangle = 12cm

Perimeter of rectangle = 2×(l+b)

= 2× (12+8)

= 2×20

Perimeter of rectangle =40 cm

[4] 40 cm
