Question
The sum of the perimeters of a square and a rectangle is
120 metres. If the sum of the length and breadth of the rectangle is 32 cm, then find the area of the square.Solution
Perimeter of the rectangle = 2 x 32 = 64 cm Perimeter of the square = 120 – 64 = 56 cm Each side of the square = 56/4 = 14 cm Therefore, area of the square = 142 = 196 cm2
