The area of a rectangle is 81cm^2 what are the dimensions if the perimeter is minimum. What is the value of these minimum perimeter?

The perimeter is 36 cm

Step-by-step explanation:

Given;

area of the rectangle, A = 81 cm²

let the Length, = L

let the breadth = b

Perimeter, P = 2L + 2b

Area, A = Lb = 81

L = 81/9

L = 9 cm

The perimeter = 2 (L + b)

                         = 2 (9 + 9)

                         = 2(18)

                         = 36 cm
