Heres what it looks like: |dw:1335534654241:dw| but of course straight lines

2. amistre64

this is just an application of the pythagorean theorum

3. amistre64

what is the sum of the squares of the sides? 12^2 + 7^2 = ?

4. qwertyfreak

193

5. amistre64

good, then the last part is to take the sqrt of that $diag=\sqrt{193}$

6. qwertyfreak

13.892444 so my answer is 13.9

7. amistre64

correct, good job
