The perimeter of a certain pentagon is 10.5 centimeters. Four sides of this pentagon have the same length, in centimeters, h, and the other side has a length of 1.7 centimeters, as shown below.

Perimeter is calculated by adding all up the sides of the polygon. In this situation, the perimeter of the pentagon is calculated through the equation,
P = 1.7 + 5h = 10.5
Calculating for h from the generated equation will give us an answer of 1.76 cm.

Is there a picture of a graph or whatever that goes along with this?
