Answer:
The correct answer is 238.95 square inches
Step-by-step explanation:
Regular Pentagon : A quadrilateral having five sides each of equal length is called regular pentagon.
Side length of pentagon, a = 11.8 inches
[tex]\text{Area of regular pentagon = }\frac{1}{4}\cdot \sqrt{5\cdot (5+2\cdot \sqrt{5})}\times a^2\\\\\implies\text{Area = }\frac{1}{4}\cdot \sqrt{5\cdot (5+2\cdot \sqrt{5})}\times (11.8)^2\\\\\bf\implies\textbf{Area = }239\textbf{ square inches}[/tex]
Hence, The correct answer is 238.95 square inches as it is approximately equal to 239 square inches.
Answer:
The answer is 477.9
Step-by-step explanation:
What you're going to do is base x height. Then your going to multiply you're answer to that by how many sides there are. so for this it going to be: 8.1 x 11.8 = 95.58. 95.58 x 5 = 477.9
Hope this helps!
Have an amazing day!
