Question
Perimeter of a square field is 160 meters and the area
of a rectangular field is 50% 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 = 160 => x = 40 Area of square field = 40 × 40 = 1600 m2 Area of a rectangular field = 1600 × (150/100) = 2400 m2
