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?

  • 6th G Math -

    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.

    _____ in^2 of fabric
