The Blakely family plans to plant sod (grass) in their backyard. The yard measures 250 feet by 180 feet. The family has an in-ground rectangular swimming pool in the center of the yard that measures 15 feet by 20 feet. How many square feet of sod will they need to cover the backyard?

To cover the backyard they need 44700 square foot of sod.

Step-by-step explanation:

Area of the backyard = 250 x 180 ft

= 45000 square ft.

Area of the swimming pool = 15 x 20 ft.

= 300 square ft.

Area of the backyard available for planting sod = 45000 - 300

= 44700 square ft.

To cover the backyard they need 44700 square foot of sod.
