9.25 feet.

Step-by-step explanation:

Given:

Chandni has 3 pieces of orange yarn that are 1.25 feet long each  and 2 pieces of blue yarn that are 2.75 feet long each.

She uses all 5 pieces of yarn for an art project.

Question asked:

What is the total length of yarn, in feet, that Chandni uses for her art project ?

Solution:

By unitary method:

Length of 1 piece orange yarn = 1.25 feet

Length of 3 pieces orange yarn = 1.25 feet 3 = 3.75 feet

Length of 1 piece blue yarn = 2.75 feet

Length of 2 piece blue yarn =  2.75 feet 2 = 5.5 feet

As she uses all 5 pieces of yarn for an art project:-

Total length of yarn, she uses for her art project = 3.75 feet + 5.5 feet = 9.25 feet

Thus, the total length of yarn, she uses for her art project = 9.25 feet.
