CPM Homework Help : CCA2 Problem 10-159

Two similar triangles are drawn on a piece of paper. The smaller triangle has an area of $600$ square mm and the larger triangle has an area of $960$ square mm. If the shortest side of the smaller triangle is $26$ mm, how long is the shortest side of the larger triangle?

Hint:

If the ratio of the areas is $\frac {600}{960}$ , then the ratio of the sides is $\frac{\sqrt{600}}{\sqrt{960}}$ .
