Question

Omar has $350 to spend on the garden he is designing. The triangle stones cost $20 each, and the border pieces co $5 to make. How long a path can Omar afford to make?

Answer 1

If Omar has $350 to spend on the garden he is designing, then he has possibility to buy 11 triangle stones and 26 border pieces, if the construction look like in the picture below, because $20×11 + 5×26 = 350.$

So, the length of the path is 11×3 = 33 units, if the length of a side of such triangle is 1 unit.
