Question

how much will it cost to make a gravel walk 3 m wide around and inside a square park whose area is 48841 sq.m at rs 50 per sq. m?​

Answer 1

You can put this solution on √4841m²=221m

side=sqrt%28area%29=sqrt%2848841m%5E2%29=221+m The length of the sides is 221 meters. The area inside the path will be shorter by 6 m (3 m at each end)

So the area inside the path is (215m*215m)=46225 square meters. Total area minus area inside path leaves area of path:

48841M%5E2-46225m%5E2=2616m%5E2 The area of the path is 2616 square meters.

Cost=%28R2%2Fm%5E2%29%282616m%5E2%29=R5232 ANSWER: The path will cost R5232.
