Question

find the cost of fencing of a square field of side 30m at the rate rs 80 per meter​

Answer 1

First find the perimeter of the square field

perimeter = 30 × 4 (30 + 30 + 30 + 30)

perimeter = 120 m

1 meter ----> rs 80

120 meters ------> rs X

cross multiply

X = 120 × 80

X = 9600

final answer = Rs 9600
