The area of any rectangle is:

A=xy, and a square is just a special rectangle where the two dimensions are equal. x=y=s, where s is the side length so the area of a square is:

A=s^2 we want to solve for s so

s^2=A

s=√A, and we are told that the area is 113 in^2

s=√113 in

s≈10.63 in (to nearest hundredth of an inch)

**Answer:**

73.5

**Step-by-step explanation:**

y=kx

where k is a constant

y=7

x=2

7=2k

k=3.5

what about when x=21

y=3.5*21

y=73.5

The answer is 1/2 hope it helps

Answer:x=12
