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
