Monica forgot to multiply by 1/2
The area of the fabric is 243 in.2

Explanation:
The formula for the area of a triangle is:
1/2 • base • height

Monica’s error is that she only multuplied the base and height, without multiplying 1/2 also.

The area of the fabric is 243 in.2 because:
1/2 • 18 • 27 = 243

Or you could just divide the wrong area Monica solved (486 in2) by 2. You will also get 243 in.2

Have a nice day! And mark me brainliest please!
