Write down the formula for finding the area<span> of a regular </span>polygon<span>. To find the </span>area<span> of a regular </span>polygon<span>, all you have to do is follow this simple formula: </span>area<span> = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides.</span>
Aright angle has 90degrees and 5ive fourths is 5/4
