Question

One pallet of sod covers 400 square feet. How many full pallets of sod will Buzz need to buy to have enough for his entire yard?.

Answer 1

the yard has two parts, one is a little rectangle with size 15 ft x 20 ft, and the other is a big rectangle with sides 50 ft x 30 ft

The little rectangle has area

`A_1=15ft*20ft=300ft^2`

And the big rectangle's area is

`A_2=50ft*30ft=1500ft^2`

Then, the total area is

`A=A_1+A_2=300+1500=1800ft^2`

And the number of pallets of sod Buzz needs is

`(1800ft^2)/(400ft^2)=4.5`

So, Buzz needs 4.5 pallets of sod
