The area of the regular heptagon which has a radius of approximately 27.87 cm and the length of each side is 24.18 cm is 2125 cm².
<h3>What is the area of a heptagon?</h3>
Heptagon is the closed shape polygon which has 7 sides and 7 interior angles.
The area of the regular heptagon is found out using the following formula.
![A=\dfrac{7a}{4}\cot \left(\dfrac{180}{7}\right)](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B7a%7D%7B4%7D%5Ccot%20%5Cleft%28%5Cdfrac%7B180%7D%7B7%7D%5Cright%29)
Here, (<em>a</em>) is the length of the heptagon.
A regular heptagon has a radius of approximately 27.87 cm and the length of each side is 24.18 cm. Put the value of side in the above formula,
![A=\dfrac{7\times24.18}{4}\cot \left(\dfrac{180}{7}\right)\\A\approx 2125\rm\; cm^2](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B7%5Ctimes24.18%7D%7B4%7D%5Ccot%20%5Cleft%28%5Cdfrac%7B180%7D%7B7%7D%5Cright%29%5C%5CA%5Capprox%202125%5Crm%5C%3B%20cm%5E2)
Hence, the area of the regular heptagon which has a radius of approximately 27.87 cm and the length of each side is 24.18 cm is 2125 cm².

Answer:
14.25 units
Step-by-step explanation:
Area of a square= ![l*b= (x-3)(x-3)=x^{2}-3x-3x+9=x^{2}-6x+9](https://tex.z-dn.net/?f=l%2Ab%3D%20%28x-3%29%28x-3%29%3Dx%5E%7B2%7D-3x-3x%2B9%3Dx%5E%7B2%7D-6x%2B9)
![x^{2}-6x+9=126.5625](https://tex.z-dn.net/?f=x%5E%7B2%7D-6x%2B9%3D126.5625)
![x^{2}-6x-117.5625](https://tex.z-dn.net/?f=x%5E%7B2%7D-6x-117.5625)
Solving the equation using quadratic equation then as attached
x=14.25 units
To prove
x-3=14.25-3= 11.25 units
area=11.25*11.25=126.5625 sq units
