Hudson wants to write a letter to his friend. He took out square paper which covers the total area of 225 feet^2
.
What is the length of any side of the paper?

length = 15 feet.

Step-by-step explanation:

This paper is 15 feet across on any side. Who will deliver this monster?

Area = s^2 where s is the length of 1 side.

Area = 225 feet^2  (You sure this isn't inches).

s^2 = area

s^2 = 225        Take the square root of both sides of the equation.

sqrt(s^2) = sqrt(225)

s = 15

answer: b.

step-by-step explanation:

it is b. cause the equations are put in the right category

b.an increase in a causes b to decrease
