x2 + 1

Answer 1

Do you know the formula for solving for the area of a square?

Answer 2

nope

Answer 3

The formula for that is A = s^2, where A is the area and s is the length of the side.

Answer 4

still dont get it

Answer 5

In order to solve for the are of square, you just have to square the length of its side. And that's it. For example, you have a square with side=4, then the area is 16square units.

Answer 6

still dont get it

Answer 7

side = 4
solving for area, you have to square it. meaning, you have to times the side to itself.
Therefore, A = 4*4 = 16

Answer 8

In your case, the side is equal to x+1. Therefore, what are you going to do?

Answer 9

\[x ^{2}+1\]

Answer 10

is that the answer
