Jim's backyard is a rectangle that is 15 5/6 yards long and 10 2/5 yards wide. Jim buys sod in pieces that are 1 1/3 long and 1 1/3 yards wide. how many pieces of sod will Jim need to but to cover his backyard with sod?

The are of his backyard is 10.4 times 15.83 or 164.632 yd^2

the sod piecs are 1.33 by 1.33 or 1.78 yd^2

so divide 164.632 by 1.78 or

164.632/1.78=92.5 pieces of sod

if he is buying the sod in pieces, he will have to buy 93 pieces because he can't buy 1/2 sod
