Perimeter of right trinangle with longer leg 2s ?
Source: Beat The GMAT — Problem Solving |
I dont understand, the a 30-60-90 triangle should be:
s+2s+s√3 then it should be 3s+s√3 = s(3+√3)
s+2s+s√3 then it should be 3s+s√3 = s(3+√3)
the answer is C.cartera wrote:I dont understand, the a 30-60-90 triangle should be:

i think as the question says the longer side and not the longest, the trick is there.
So as figured out, the sides are in ratio 1:√3:2
so C matches the perimeter.
