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

1620
`in^(2)`

Step-by-step explanation:

A =
`((base)(height))/(2)`

A =
`((18)(36))/((2))`

A =
`(648)/(2)`

A = 324

324 x 5 = 1620
`in^(2)`
