The area of a square can be found using the equation A=swhere A is the area and s is the measure of one side of the square. Match the equation for how to solve for the side length of a square to its description
A square has an area of 81 in?
S = V 812 in
S=V81 in
S = 812 in
S = 81 in

what's the question?

step-by-step explanation:

there is no question.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
