Answer:
49.25 feet
Explanation:
1 yard = 3 feet
A school club needs 350 feet of rope for a project.
They have 4 pieces of rope that are each 14 yards in length.
14 yards = 14 × 3 = 42 feet
4 ropes of 42 feet = 42 × 4 = 168 feet
1 piece of rope that is 10.5 yards in length = 10.5 × 3 = 31.5 feet
1 piece of rope that is 101.25 feet in length = 101.25 feet
Total rope in length = 168 + 31.5 + 101.25 = 300.75 feet
They need additional rope = 350 - 300.75 = 49.25 feet.
They need additional 49.25 feet rope for their project.
