Question
Length and breadth of a rectangle are 30 cm and 24
cm. If area of a square is 144 cm² less than that of rectangle, then find the perimeter of square.
Solution
Area of rectangle = 30 × 24 = 720 cm² Area of square = 720 - 144 = 576 cm² Side of square = √576 = 24 cm So, perimeter of square = 4 × 24 = 96 cm
