Answer 1

\[a^2 + b^2 = c^2\]In this image, AE is your 'c' and AF is one other side (a or b).
\[a^2+11^2=61^2\]solve for 'a' then double it to get the full length of FG.

Answer 2

thanks :) okay hold on

Answer 3

You're welcome :)

Answer 4

okay i got 121 :) so do i divide 121 and 61 next?

Answer 5

61^2 = 3721
11*11 = 121 so plug those into the equation.\[a^2+121=3721\]
All you need to do is subtract the 121 to the right side, then sqrt both sides to find 'a'

Answer 6

oh okay i did that :) i subtracted them and got 3600

Answer 7

do i square 360 next?

Answer 8

i mean 3600

Answer 9

fine ;(

Answer 10

Sorry I was away, yes once you get 3600, you simply need to square root it. thus a = 36
