A square pond is to be built in a park. The pond is 50 meters long and 50 meters wide. There should be a tile sidewalk 5 meters wide all around the pond. The tile is sold in crates of 45 square meters of tile. What will the tile cost if the cost of each box of tile is $74?

area of the pond is 50*50 = 2500 square meters

 the walkway is 5 meters wide so the outside dimensions would be 60 meters by 60 meters

 area of that is 60 *60 = 3600 meters

 area of walkway is 3600 - 2500 = 1100 square feet

number of crates needed: 1100 / 45 = 24.44, round up to 25 crates

25 crates x $74 each = $1,850 total
