Question

Brian is making 5 triangular flags, each with the dimensions shown below.

A triangle has a base of 18 inches and a height of 36 inches.

How much fabric will Brian need to make the 5 flags?

Answer 1

Answer:

1620 $in^{2}$

Explanation:

A = $\frac{(base)(height)}{2}$

A = $\frac{(18)(36)}{(2)}$

A = $\frac{648}{2}$

A = 324

324 x 5 = 1620 $in^{2}$
