Patty is building a rope ladder for a tree house. She needs two 5-foot pieces of rope for the sides of the ladder. She needs 5 pieces of rope, each 18 inches long, for the steps. How many feet of rope does Patty need to make the ladder?

Respuesta :

Length of Rope, for Sides of the Ladder = 5 * 2 = 10 Feet

Length of Rope, for steps of the Ladder = 18 * 5 = 90 inch.

We know, 1 Feet = 12 inch

So, 90 inch = 90/12 = 7.5 Feet

Total Rope Length = 10 + 7.5 = 17.5 Ft

In short, Your Answer would be: 17.5 Feet

Hope this helps!
