The school pep squad members wanted to make rectangular spirit flags with bases of 7 inches and heights of 8 inches. Each flag is divided evenly into a red triangle and a white triangle.
How much fabric would be needed to make the white triangle for 100 spirit flags?

Find the area of one rectangle flag.
7in x 8in = ?
Divide the area by 2 (because half of the flag is white, the other half is red)
That is the area of one white triangle.
You need 100 flags so multiply that number by 100.
