Question

Can you give me proably a little step by step to the answer so I can understand it a bit more?

Answer 1

Answer:

120 square inches.

Step-by-step explanation:

• This is a regular octagon. (It has 8 equal sides).
• You have enough information to find the area of 1 triangle.
• label the bottom line as 5.
• Draw two lines from the center to each end of the bottom 5 inch line.
• That gives you 1 triangle. Find the area of that 1 triangle.

• Area = 1/2 b * h
• b = 5
• h = 6
• Area = 1/2 * 5 * 6
• Area = 15.

• Now here's the actual answer.
• You have 8 such triangles.
• The area of the octagon is 8 * 15 = 120 square inches.
