Question

If there's a grass area in the shape of a square and one side is 8 metres how much would it cost to fill the grass with fresh gravel at $5/metre

Answer 1

The answer is 320. The area = 8 times 8 because all the sides are equal then once you get the answer from multiplying 8 by 8, which is 64, you multiply 64 by 5. Then you get the answer of $320
