# How many square feet is a 14 foot octagon?

**feet**and hence the area of the

**octagon**is w

^{2}- 2 b

^{2}

**square feet**. Since w = 12

**feet**, all that is needed is to find b.

**square feet**which is approximately 119

**square feet**.

Considering this, how do you find the dimensions of a octagon?

Since there are as many of these triangles as the polygon has sides (eight for an **octagon**), you have to multiply the area of this triangle by the number of sides. You will obtain the total area of the **octagon**: area of **octagon** = 8 * base * height / 2 = perimeter * apothem / 2 .

One may also ask, how do you find the area of a octagon with a radius? **Find the area** of a regular **octagon** inscribed in a circle with **radius** 1 unit. Break the **octagon** into 8 congruent triangles. You will **find the area** of one triangle and multiply that by 8 to **find the area** of the whole **octagon**. Draw in the height for one of the triangles.

Also Know, how do you find the side length of an octagon with the diameter?

Multiply the **diameter**, which is the perpendicular **length** between two parallel **sides**, by 0.414 to **calculate** a **side's length**. For example, the **diameter** measures 5 inches and 5 inches multiplied by 0.414 equals 2.07 inches.

What are the dimensions of an octagon?

A regular octagon is a geometric shape with 8 equal lengths and 8 equal **angles**. The sum of the interior **angles** of a regular octagon is 1080 degrees, which makes each angle equal to 135 degrees in measure.
