Question

The scale factor of two triangles is 2:5. If the smaller triangle has side length of 30, what would be the length of the corresponding side on the bigger triangle?

Answer 1

75

Explanation:

From the way you've typed the question, it would appear that the ratio of the size of the smaller side to the ratio of the size of the larger side is 2:5.

Therefore, if the smaller side is 30, you can use the ratio the find the larger side:

`S:L\\2:5\\\\`

(×15 to make the smaller side 30)

`30:75`

Therefore, the bigger triangle would have side length 75.
