Asked by keyna

if the lengths of the sides of one triangle are 2 inches 5 inches and 7 inches respectively in the shortest leg of a similar triangle is 4 inches what is the perimeter of the second triangle in inches?
Answered by Steve
sorry - no triangle has sides of 2,5,7. That is just a straight line of length 7.

Whoever devised this problem was sadly unaware of properties of a triangle.

Anyway, supposing you have a real triangle, if the sides are doubled, so is the perimeter.
