Find half of the perimeter of the rectangle. Divide the perimeter by 2.
p = 28 cm ÷ 2 = 14 cm.
To find the length, subtract the width from half the perimeter.
a = 14 cm – 8 cm = 6 cm.
To find the area of a rectangle, you need to multiply the width by the length.
S = 8 cm * 6 cm = 48 cm².
Answer: the area of the rectangle is 48 cm².
