The area of a rectangle is 96 ππ2 . If the breadth of the rectangle is 8 ππ, find its perimeter. [1] 20 ππ [2] 48 ππ [3] 32 ππ [4] 40 ποΏ½
Area of rectangle = LΓB
96 = LΓ8
L = 96/8
Length of rectangle = 12cm
Perimeter of rectangle = 2Γ(l+b)
= 2Γ (12+8)
= 2Γ20
Perimeter of rectangle =40 cm
[4] 40 cm
