Thread: Word Problem - Need Assistance

The Andersons are buying a new home. They need to fence the yard because they have dog. The yard is 72 ft by 120 ft. Each fencing section is 8ft. How many sections will they need?

perimeter of yard = 2 * (72 +120) = 384

Numer of sections required = 384/8 = 48

In real life ,I think should be (72+2*120 )/8
