Area of the square = 576 cm2 Length of each side of the square = √576 = 24 cm Area of the rectangle = 576 + 172 = 748 cm2 Length of the rectangle = 10 + 24 = 34 cm So, area of rectangle = length × breadth = 34 × breadth = 748 cm2 So, breadth of the rectangle = 748/34 = 22 cm Therefore, perimeter of the rectangle = 2 × (length +breadth) = 2 × (22 + 34) = 112 cm
