Daniela built a garden in her backyard that measures 14 feet by 13 feet. She has 26 feet of fencing already, and needs to purchase more to build a fence around the garden. The store sells fencing in lengths of 4 feet. How many lengths of fence does she need to buy to finish the fence?

Respuesta :

first, we need to know the perimeter of the garden

P=2(14)+2(13)=54 ft

then we need to know how many lengths she needs to buy

54-26=28 ft

and we need to remember that in the store only sells fencing lengths of 4 feets

28/4=7

she needs to buy 7 to finish the fence
