Find the area of a regular polygon with 7 sides that has a side length of 6 inches and an apothem of 8 inches

We can always split a regular polygon with sides into triangles, whose base is the side of the polygon and whose height is the apothem of the polygon. So, the sum of the areas of all these triangles is

where is the number of sides, is the side length, and is the apothem length.

So, you just need to plug you values in: in your case, you have

So, the formula becomes

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
