Ah, direct variation/proportion.
That is simply a linear equation with a y-intercept of 0.
So... let's solve this.
Simply put, a direct variation multiplies the x-value by a constant to get the y-value.
Let's take the point

on this graph and solve for the constant of proportionality:

We easily solve that and get our answer of

. (B)
The sides could be 10.2 inches or 15.7 inches.
