Step-by-step explanation:
Area of the pentagon: 342 cm2
Step-by-step explanation:
The figure of the pentagon is missing: find it in attachment.
The area of the pentagon can be seen as the area of 5 equal triangles, each of them having a base equal to the length of the side of the pentagon,
L = 14.1 cm
and the height of each triangle can be found by using Pythagorean's theorem:
![h=\sqrt{12^2-(\frac{L}{2})^2}=\sqrt{12^2-(\frac{14.1}{2})^2}=9.7 cm](https://tex.z-dn.net/?f=h%3D%5Csqrt%7B12%5E2-%28%5Cfrac%7BL%7D%7B2%7D%29%5E2%7D%3D%5Csqrt%7B12%5E2-%28%5Cfrac%7B14.1%7D%7B2%7D%29%5E2%7D%3D9.7%20cm)
The area of each of the 5 triangles is
![A'=\frac{1}{2}Lh](https://tex.z-dn.net/?f=A%27%3D%5Cfrac%7B1%7D%7B2%7DLh)
Therefore, the area of the pentagon is 5 times this area:
