Question

LO.The ratio of the lengths of the sides

of a triangle is 2:4:5. There is a
second triangle (that is similar to
the first) whose shortest side is 6.
What is the perimeter of the second
triangle?

Answer 1

34

Explanation:

The scale factor is 3

2 x 3 = 6 So the other sides are multiplied by 3

4 x 3 = 13

4 x 3 = 15

Add the 3 sides together

6 + 13 + 15 = 34
