Answer:

Therefore the smallest parameters is (6,6) and a dimension of 24 inches

Explanation:

From the question we are told that

area of dimension is
A=36

Generally the perimeter of rectangle is given as


x,y=36

Given by


(x,y)=2x+2y

Mathematical solving for perimeter of rectangle


x=(36)/(y)


f(y)= 2(36)/(2) +2y\\f(y)= (72)/(y) +2y

Generally in finding minimum perimeter


f'(y)=(-72)/(y^2) +2=0\\


y=6


f(6,6)=2(6)+2(6) \\f(6,6)=24 inches

Therefore the smallest parameters is (6,6) and a dimension of 24 inches
