Question

Leilani hung a triangular pennant for her favorite baseball team in her room as shown below.

If the area of Leilani’s pennant is 82.65 in.2, what is the measure of the base in inches?

Answer 1

Explanation:

recall the area of a triangle is Area = 1/2* Base* height

then we know the height, and the area solve for the base

I'll do the algebra symbolically so you can see how

A = 1/2 *B * H ( start here)

2A/H = B ( move to here )

Now plug in what you know on the left side

2*82.65/17.4 = base

9.5 = base :)
