A backyard measures 30 feet by 40 feet. If the owner builds a fence around, about how many feet of fencing will be needed?
Troyanec [42]

Answer:

140 feet

Step-by-step explanation:

You will need to find the perimeter of the backyard to find how many feet of fencing will be needed

the formula for perimeter is: 2l+2w

So 2 times 30 is 60

with 2 times 40 80

60+80 is 140

Thus you will need 140 feet to cover the backyard

Hope this helps!
