Riley’s family is putting a rectangular pool in his backyard. the dimensions of the pool will be 12 ft. by 24 ft. by 5 ft.

the contractor building the pool needs to know how much lining he needs before starting to pour the concrete. how many square feet of liner will he need? (hint: the liner will need to cover all the inside concrete surfaces of the pool, but not the top of the pool.)

The surface area not including the top of the pool would be 748 ft(not sure if the teacher want you to add square to the end of it or not) .so 12*5 is 60 ,*2 =120. 24*5 =120. 120*2= 240. 24*12=288. so 288+240+120=748 ft(this would be the surface area of the pool.so if you need the volume of concrete needed to make the pool times the needed with of the concrete by the area ∆make sure if the needed thickness needed is in inches turn the area from feet to inches by multiplying it by 12 )

200 miles.45 x 3 (charge per day times days)135$205$ - 135$ = 70$0.35x = 70divide both sides by 0.35200
