What is the area of a regular dodecagon with a side length of 9 centimeters? Round your answer to the nearest tenth.

Step-by-step explanation:

A do-decagon is a polygon with 12 straight sides and 12 equal angles.

-The general formula for finding area of a do-decagon is given as:

where s is the sides length.

-Given the sides dimension is 9cm, the area is calculated as;

Hence, the do-decagon's area is

$2,703.06

step-by-step explanation:

add: $2,687.44+ $2,613.09+$2,808.64= $8,109.17

divide by 3 because you added 3 numbers.

$8,109.17/3=

answer: $2,703.06
