- Choice K
To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.
The perimeter of a rectangle is equal to the sum of all the sides. However, since a rectangle's opposite sides are congruent, we only need to know the length and width.
L × W = 32
L = 2W
⇒ W = 4, L = 8
⇒ Perimeter = (4 + 8) × 2 = 24
