<h3>What is a regular octagon?</h3>It is a polygon that has eight equal sides. In a regular octagon, the opposite sides are parallel. And its diagonals are also equal and intersect at mid-point.
Given
A regular octagon has a radius of 6 ft and a side length of 4.6 ft.
We know the formula for the regular octagon.
Area of the regular octagon = 2(1 + ) a²
Where a be the side of a regular octagon.
Then the area of the regular octagon will be.
Thus, the area of the regular octagon of side length be 4.6 is 102 ft².

Answer:
481
Step-by-step explanation:
There are several ways you can get there.
1. There are only 13 numbers, so you can write them down and add them up.
25 + 27 + 29 + ... + 47 + 49 = 481
__
2. You can use the formula for the sum of an arithmetic sequence. This one has a starting value of 25, an ending value of 49, and 13 terms.
Sum = ((start) + (end))/2 × (number of terms) = (25 +49)/2×13 = 481
__
3. You can use a formula for the terms of the series and evaluate the sum.
an = 25 +2(n -1) = 2n +23
