<h3>Answer: 4 square inches</h3>

Explanation:

Square the linear scale factor to get 5^2 = 25

This means that,

new area = 25*(old area)

We take this idea in reverse to find the old area

old area = (new area)/25

old area = (100 sq inches)/25

old area = 4 square inches

A piece of fabric is 2 yards long Marcus puts one patch at each end of the fabric and at each quarter foot mark how many patches

klio [65]

Conversion.
1 yard = 3 feet

So the fabric has 2 yards. Then the size of the patch is 1/4 foot.
So the number of patches that Marcus used is..
= 3 * 2
= 6 / (1/4)
= 24 patches.

So a total of 24 patches Marcus used.
