15.5 feet

Explanation:

Given:

Patty is building a rope ladder tree house she needs two 4 foot pieces of rope for the sides of the ladder.

She needs 6 pieces of rope each 15 inches long for the steps.

Question asked:

How many feet of rope does patty need to make the ladder ?

Solution:

She needs for the sides of the ladder = Two 4 foot pieces of rope

= 2
`*` 4 feet = 8 feet

She needs for the steps of the ladder = 6 pieces of 15 inches long rope

= 6
`*` 15 inches = 90 inches

Convert 90 inches into feet:-

12 inches = 1 feet

1 inches =
`(1)/(12) \ feet`

90 inches =
`(1)/(12) *90=(90)/(12) =7.5\ feet`

Patty needs total rope = 8 feet + 7.5 feet

= 15.5 feet

Thus, Patty needs 15.5 feet of rope to make the ladder.
