The area of a square = 1225 cm2 Let the side of the square = x cm. Hence, x2 = 1225 x = 35 cm Diagonal of the square = x √2 = 35 √ 2 cm Length of the rectangle (L) = 80% of 35√2 cm = 28√2 cm Perimeter of the rectangle = 94√2 cm 2 (L + B) = 94√2 cm L + B = 47√2 cm 28√2 + B = 47√2 B = 19√2 cm Area of the rectangle = L×B = 28√2*19√2 cm = 1064 cm2
