you need to use the Pythagorean theorem to find the length of the hypotenuse first

Okay. Let me look at the question again.

6^2+8^2

$\sqrt{100} = 10$

so |dw:1363214892381:dw|

then u multiply by 2.5 and add them up,no?

I got (C)

10. AriPotta

yea, but you could just add 6, 8, and 10 then multiply that by 2.5

Oh,ok. TY.

12. AriPotta

yea it's c. good job
