The area of the polygon is 27 mi 2 what is the formula that shows the length of side a​

option 1

Step-by-step explanation:

the polygon is made up of three squares

the area of the polygon is the sum of the area of the three squares

Area of a square = length²

a²

Area of the polygon = a² + a² + a² = 3a²

3a²  = 27

a² = 27/3

a² = 9

a = 3

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
