Question

Patricia and Greg are both planting rectangular flower gardens. Patricia’s garden measures 7 ft × 12 ft .Greg’s garden measures 8 ft. × 15 ft. Each garden will have a fence put around it. Including tax, the fencing materials cost $1.25 per foot.

Answer 1

Patricia = $47.5 ;

Greg = $57.5 ;

$10

Explanation:

Perimeter of a rectangle : 2(l + b)

Patricia :

7ft * 12 ft

2(7 + 12) = 2(19) = 38 ft

Total fencing cost :

1.25 * 38 = $47.5 ft

Greg:

8ft by 15ft

2(8 + 15) = 2(23) = 46ft

Total fencing cost :

1.25 * 46 = $57.5

Difference in cost :

57.5 - 47.5 = $10
