Question

A triangle has side lengths of (3.9f - 1.2g) centimeters, (9.9f + 8.1h) centimeters, and (2.4h - 9.4g) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

look at the question shown here to answer correctly.​

Answer 1

`Perimeter = 13.8f - 10.6g + 10.5h`

Step-by-step explanation:

Given

`Side_1 = (3.9f - 1.2g)`

`Side_2 = (9.9f + 8.1h)`

`Side_3 = (2.4h - 9.4g)`

Required

Determine the perimeter of the triangle

The perimeter is solved using

`Perimeter = Side_1 + Side_2 + Side_3`

`Perimeter = 3.9f - 1.2g + 9.9f + 8.1h + 2.4h - 9.4g`

Collect Like Terms

`Perimeter = 3.9f + 9.9f- 1.2g - 9.4g + 8.1h + 2.4h`

`Perimeter = 13.8f - 10.6g + 10.5h`

Hence;
