Answer:

15.5 feet

Step-by-step 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 [tex]\times[/tex] 4 feet = 8 feet

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

                                                               = 6 [tex]\times[/tex] 15 inches = 90 inches

Convert 90 inches into feet:-

12 inches = 1 feet

1  inches = [tex]\frac{1}{12} \ feet[/tex]

90 inches = [tex]\frac{1}{12} \times90=\frac{90}{12} =7.5\ feet[/tex]

Patty needs total rope = 8 feet + 7.5 feet

                                     = 15.5 feet

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