Question
The sum of the perimeters of a square and a rectangle is
128 metres. If the sum of the length and breadth of the rectangle is 34 cm, then find the area of the square.Solution
Perimeter of the rectangle = 2 x 34 = 68 cm Perimeter of the square = 128 – 68 = 60 cm Each side of the square = 60/4 = 15 cm Therefore, area of the square = 152 = 225 cm2
