greg is installing gutters on his rectangular shed that measures 8 feet by 8 feet he has 20 feet of gutter already and needs to purchase more to complete the gutter all the way around the shed. the store sells gutters in length of 2 feet. how many lengths of gutter does he need to buy to finish the shed?

6 more lengths of gutter

Step-by-step explanation:

First, find the perimeter of the shed.

Use the perimeter formula, P = 2l + 2w

Plug in the length and width, then solve:

P = 2l + 2w

P = 2(8) + 2(8)

P = 16 + 16

P = 32

So, the perimeter is 32 feet.

Find how much more he needs by subtracting 20 from this, since he already has 20 feet of gutter.

32 - 20

= 12

So, he needs 12 more feet.

The store sells gutters in lengths of 2 feet, so divide this by 2:

12/2

= 6

So, he will need 6 more lengths of gutter
