Question

A triangle has sides 5,12 and 13. The triangle was enlarged by a scale factor of 300%. What are the lengths of the sides of the new triangle?

Answer 1

The answer is 15, 36, 39

The math behind the answer is you must change the 300% to a decimal, which is 3. So then you multiply each side by 3

Answer 2

15, 36 and 39.

Explanation:

The length of sides of the original triangle are 5, 12 and 13.

It is given that the triangle was enlarged by a scale factor of 300%.

It means the sides of new triangle is 3 times of the corresponding sides of original triangle.

Multiply each side of original triangle by 3.

`5* 3=15`

`12* 3=36`

`13* 3=39`

Therefore, the length of sides of the new triangle are 15, 36 and 39.
