Question
Perimeter of a square field is 120 meters and the area
of a rectangular field is 65% more than that of the square field. Find the area (in m2) of a rectangular field.Solution
Let the length of each side of the square field be ‘x’ meters. => 4a = 120 => x = 30 Area of square field = 30 × 30 = 900 m2 Area of a rectangular field = 900 × (165/100) = 1485 m2
