This is seventh grade math so if you are not in seventh grade or up, I am not sure if you would be comfortable with this kind of thing

Answer 1

The answer is 243 patches.

Explanation:

Area of a rectangular piece of fabric = 15 × 9 = 135 cm²

Area of 27 pieces of fabric = 135 × 27 = 3645 cm²

Number of patches can be cut from = 3645 ÷ 15 = 243
