Question

A scale drawing is made of a triangle with side lengths 3, 4, and 5 using a scale factor of 1.5. Select all of the side lengths of the newly created triangle. A. 5.5 B. 6.5 C. 6 D. 4.5 E. 7.5

Answer 1

Explanation:

A

Answer 2

Given:

Original side lengths are 3, 4, and 5.

Scale factor = 1.5.

To find:

The all of the side lengths of the newly created triangle.

Solution:

We need to multiply the side lengths with the scale factor to get the side lengths of the newly created triangle.

The original side lengths are 3, 4, 5 and scale factor is 1.5. So, side lengths of the newly created triangle are

`3* 1.5=4.5`

`4* 1.5=6`

`5* 1.5=7.5`

So, the side lengths of the newly created triangle are 4.5, 6 and 7.5.

Therefore, the correct options are C, D and E.
