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 30 m, then find the area of the square.Solution
Perimeter of the rectangle = 2 x 30 = 60 m Perimeter of the square = 120 β 60 = 60 m Each side of the square = 60/4 = 15 m Therefore, area of the square = 152Β = 225 m2
