Question

A triangle with side lengths of 5, 12, and

15 centimeters is similar to another triangle.
9 The longest side of the other triangle has
length 24 centimeters. What is the perim-
eter, in centimeters, of the larger triangle?

Answer 1

51.2

Explanation:

`(15)/(5) = (25)/(x)`

15x = 120

x = 8

so now we know that 2 sides of the bigger triangle are 24 and 8

now

`(8)/(x) = (5)/(12)`

96 = 5x

x = 19.2

19.2 + 24 + 8
