Answer 1

Area and Perimeter problem

Given: The area of the square compound is 1225 sq. m. The fencing of the compound costs Rs. 200 per meter.

To find: What will be the total cost of fencing?

Solution:

• The area of the square compound is 1225 sq. m
• Then the length of each side is = √1225 m
• = 35 m
• In order to build fences, we must find its perimeter.
• The perimeter of the square compound is
• = 4 * length of each side
• = 4 * 35 m
• = 140 m
• Thus the total cost of fencing the square compound at Rs. 200 per meter is
• = Rs. 140 * 200
• = Rs. 28000

Answer: The total cost of fencing is Rs. 28000 .
