Method 1: In order to find out the area of an octagon with a radius of 4 feet, we have to split the whole figure into 8 equal isosceles triangles.
Therefore,
We will find out the area of one triangle and multiply the area with 8 to, figure out the area of the whole octagon there are 8 similar triangles and all of them will have the same area.
Method 2: From method 1, it would take time as there are too much of calculation, therefore we would go for the shortcut using the formula:
Area = 2√2 × r²
where r<span> is the radius of the octagon.
Substituting the values,
We get:
</span>Area = 2√2 × 4²
Area = 2√2 × 16
Area = 2× 1.41 × 16
Area = 2.828 × 16
Area = 45.25
Rounded to the nearest tenth:
Area = 45.3 ft²

The slope-intercept equation is y=mx+b.
The slope formula is
Our three points are (5,5), (-5,-7) and (0,-1)
Using our slope formula our slope becomes
Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So, . When we solve for x and y, we get -1=0+b, or b=-1.
When we plug that back into the equation, we get.
