Similar triangles have sides that are proportional.
The shortest side of the first rectangle is 5, so that corresponds to the shortest side of the new one which is 15.
The side lengths are 5 and 15, so the ratio is 1 to 3.
The longest side length of the first triangle is 10, so the longest side of the new triangle must be three times that, or 30.
The third side of the first triangle is 6, so the third side of the new triangle must be three times that, or 18
check ratios:
5%2F15=6%2F18=10%2F30
0.33=0.33=0.33
