Question

What is the answer to 99, please explain

Answer 1

Ratio of sides are x : x*root(3) : 2x
which means smallest side is x
largest side is 2 x or two times x

if you're wondering why root(3) isnt bigger, then root(4) is equal to 2
and root(4) is greater than root(3)

ok, if the smallest side is 5  (or x=5)
then the largest side is 2*5

2 times 5 =?
