What’s the area of the regular polygon picture below

Given:

Regular polygon.

Side length = 18 in

To find:

The area of the regular polygon.

Solution:

Let us first find the apothem (length from center to side).

Apothem formula:

where s is side length and n is number of sides.

number of sides (n) = 6

The value of

in

Area of regular polygon:

where p is perimeter of polygon and a is apothem.

square inches.

The area of the regular polygon is 841.78 square inches.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
