The area of a rectangle is 28 square inches. If the length is 4 inches, what is the perimeter of this rectangle?

Perimeter of the rectangle, P = 22 inches

Step-by-step explanation:

Let A represent the area, L, the length, W, the width and P, the perimeter of the rectangle

Area of a rectangle, A = LW ... eq 1

Perimeter of a rectangle P = 2 (L + W) ... eq 2

A = 28 sq inches

L = 4 inches

Slotting in the values of A and L in eq 1

28 = 4W

28 / 4 = 4W / 4

7 = W

Therefore, W = 7 inches

Now, lets slot in the values of W and L in eq 2

P = 2 (4 + 7)

P = 2 (11)

P = 22 inches
