Question

a rectangular park is 40m long and 30m wide.a path 2.5m wide is constructed outside and around it.Find the area of the path and cost of cementing the path at rate 200$ per meter square

Answer 1

Area: 181.25 sq meters

Cost: $36,250

Explanation:

Multiply 40 by 30 to get the inside of the path. Then add 2.5 to both dimensions to get the outside of the path. Then subtract the inside from the outside of the path to get 181.25.

To find the cost multiply 181.25 by 200 to get 36,250.
