The equation for the graph passing through the points (0, 0) and (3, 12) is y = 4x.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
From the graph, using the points (0, 0) and (3, 12):
y - 0 = [(12 - 0)/(3 - 0)](x - 0)
y = 4x
The equation for the graph passing through the points (0, 0) and (3, 12) is y = 4x.

Using the Pythagorean theorem, we can calculate the apothem of the pentagon.
We have then:
![a = \sqrt{12 ^ 2 - (\frac{14.1}{2}) ^ 2}\\a = 9.7](https://tex.z-dn.net/?f=%20a%20%3D%20%5Csqrt%7B12%20%5E%202%20-%20%28%5Cfrac%7B14.1%7D%7B2%7D%29%20%5E%202%7D%5C%5Ca%20%3D%209.7%20%20%20%20)
Then, the area of the pentagon is given by:
![A = 5 * (\frac{1}{2}) * (L) * (a)](https://tex.z-dn.net/?f=%20A%20%3D%205%20%2A%20%28%5Cfrac%7B1%7D%7B2%7D%29%20%2A%20%28L%29%20%2A%20%28a%29%20%20%20)
Where,
L: side of the pentagon
a: apotema
Substituting values:
![A = 5 * (\frac{1}{2}) * (14.1) * (9.7)\\A = 341.925](https://tex.z-dn.net/?f=%20A%20%3D%205%20%2A%20%28%5Cfrac%7B1%7D%7B2%7D%29%20%2A%20%2814.1%29%20%2A%20%289.7%29%5C%5CA%20%3D%20341.925%20%20%20)
Rounding the nearest whole we have:
![A = 342 cm ^ 2](https://tex.z-dn.net/?f=%20A%20%3D%20342%20cm%20%5E%202%20%20)
Answer:
the approximate area of the regular pentagon is:
![A = 342 cm ^ 2](https://tex.z-dn.net/?f=%20A%20%3D%20342%20cm%20%5E%202%20%20)
