OpenStudy (joannablackwelder):

Area of a triangle is 1/2 base times height where the base and height are at right angles.

OpenStudy (hanner_b_nanner):

So would it be 15.5?

OpenStudy (joannablackwelder):

How did you get that?

OpenStudy (joannablackwelder):

What do you get for the length of PQ?

OpenStudy (hanner_b_nanner):

PQ is 8

OpenStudy (hanner_b_nanner):

ohhhh, the base is 4. So 1/2 would be 2, andn 2x8=16! Is that right?

OpenStudy (joannablackwelder):

:) Right!

OpenStudy (hanner_b_nanner):

I was counting the wrong side. Thank you! :D
