Question

Alex is making 12 pennants for
the school fair. The pattern he is using to
make the pennants is shown in the figure.
The fabric for the pennants costs $1.25 per
square foot. How much will it cost Alex to
make 12 pennants?

Answer 1

figure the area of one pennant.
Multiply it by 1.25 to find its cost
Multiply that result by 12, for 12 pennants.

Finding the area is your penance for not describing the pennants!
