you need to find the bottom length so you need to use the pythaorean theorem again to find the side length

OpenStudy (anonymous):

I think it's d btw

OpenStudy (anonymous):

its not

OpenStudy (anonymous):

8^2 + 4^2 is 80 the square root of 80 is 8.9

OpenStudy (anonymous):

no, in this case 8 is the c value of the pythagorean theorem

OpenStudy (anonymous):

oh dang it.

OpenStudy (anonymous):

so its a^2 + 4^2 = 8^2

OpenStudy (anonymous):

ohhh, okay

OpenStudy (anonymous):

so its c (im totally not guessing)

OpenStudy (anonymous):

nope

OpenStudy (anonymous):

after that equation a would be the square root of 48

OpenStudy (anonymous):

so multiply that by 4

OpenStudy (anonymous):

i know i got that far D:

OpenStudy (anonymous):

because 4 is a side length and square root of 48 is a side length multiply them together and you have the area

OpenStudy (anonymous):

b?

OpenStudy (anonymous):

\[4\times \sqrt{48}=?\]

OpenStudy (anonymous):

13.85 13.9

OpenStudy (anonymous):

its 27.7 which rounded is 28 inches, so A

OpenStudy (anonymous):
