## Suggestion

The perimeter of a given triangle, whose sides are in the ratio of $3 : 4 : 5$, is greater by $\quantity{4}{ft.}$ than that of a given square. The area of the square is greater by $\quantity{25}{sq.ft.}$ than that of the triangle. Find the lengths of the sides of the square and of the triangle.

What do we know about a triangle with side lengths 3, 4 and 5?

Can we use the information in the question to form a pair of simultaneous equations?

In this applet, the perimeters differ by $4$ and the sides of the triangle are $3a$, $4a$ and $5a$.
