asked • 05/31/18Need to explain/justify how I got the answer

the city wants fencing around the playground, the basketball court, and the tennis court in the new park. The playground is 100 feet by 100 feet, the basketball court is 94 feet by 50 feet, and the tennis court is 78 feet by 36 feet. If the fencing cost $3.25 a foot, how much will the city pay for the fencing in the new park for all three areas?

So it sounds like the playground is a square, and the basketball and tennis courts are rectangles. We need to find the perimeter of each.

Playground

P=4(100)

P=400

Basketball

P=2(94)+2(50)

P=188+100

P=288

Tennis

P=2(78)+2(36)

P=156+72

P=228

400+288+228=916

916 X $3.25 a foot = $2,977
