The perimeter of a square field is 16 cm more than the

Solution

Let the width of the rectangle = x cm Then, 150% of x = 24 x = 24 × 100/150 = 16 cm Perimeter of the rectangle = 2(length + width) = 2 × (24 + 16) = 80 cm Perimeter of the square = (80 + 16) = 96 cm The sides of the square = 96/4 = 24 cm The area of the square field without street = (24)² sq. cm = 576 sq. cm The area of the square field with street = (24 + 20)² sq. cm = 1936 sq. cm The area of the street = 1936 – 576 = 1360 sq. cm The total cost of constructing the street = 1360 × 25 = Rs. 34,000
