The perimeter of a square is 96 cm. The area of a rectangle is 16 cm square less than the area of the square if the length of the rectangle is 28 cm. What is its perimeter?
Perimeter of the square = 96 cm.
Side of the square = 96/4 = 24 cm.
Area of the square = 24^2 = 576 sq cm.
Area of the rectangle = 576–16 = 560 sq cm.
Length of the rectangle = 28 cm.
Width of the rectangle = 560/28 = 20 cm.
Perimeter of the rectangle = 2(28+20) = 96 cm.
Answer:
area= 560 sq km
