Answer: See explanation

Explanation:

First we have to calculate the perimeter of the work of art. This will be:

= 2(14 inches + 20 inches)

= 2 × 34 inches

= 68 inches

1. If each paper clip is 1 3/4 inch long, how many paper clips would she need?

This will be:

= 68 ÷ 1 3/4

= 68 ÷ 7/4

= 68 × 4/7

= 272/7

= 38 6/7

= 39 paper clip approximately.

2. How many paper clips are needed if the paper clips are spaced 1/4 inch?

This will be:

= 68 ÷ (1 3/4 + 1/4)

= 68 ÷ 2

= 34 paper clips
