Respuesta :

Zos
Jim's backyard:
15 5/6 yd long
10 2/5 yd wide

Sod pieced:
1 1/3 yd long
1 1/3 yd wide

Area of backyard:
15 5/6 times 10 2/5 =
164 2/3 yd

Area of Sod Piece:
1 1/3 times 1 1/3 =
1 7/9 yd

Divide area of backyard by area of sod piece :
164 2/3 divided by 1 7/9 =
92 5/8

He will need to buy 93 pieces of sod to cover his backyard.
