Answer:
Perimeter of the triangle = (2.4f+4.4g-5.4h) centimeters.
Step-by-step explanation:
It is given that, a triangle has side lengths of (1.3f+2.9g) cm, (1.1f-7.7h)cm, and (2.3h+1.5g) cm.
We have to find the expression which represents the perimeter, in centimeters, of the triangle.
Perimeter of a triangle = Sum of its all the sides.
[tex]Perimeter=(1.3f+2.9g)+(1.1f-7.7h)+(2.3h+1.5g)[/tex]
On combining like terms, we get
[tex]Perimeter=(1.3f+1.1f)+(2.9g+1.5g)+(-7.7h+2.3h)[/tex]
[tex]Perimeter=2.4f+4.4g+(-5.4h)[/tex]
[tex]Perimeter=2.4f+4.4g-5.4h[/tex]
Therefore, the perimeter of the triangle is (2.4f+4.4g-5.4h) centimeters.
