To find the area of a square, remember that a square is a type of rectangle so we can use the following formula to find its area.
Area = length × width
However, since the length and width of a square are always equal, we use a special version of this formula to find the area of a square.
Instead of area = length × width, we say that the area of a square is equal to side × side or s².
I'll show an example.

Since each side of a square is the same, it can simply be the length of one side squared. So multiply the sides by one another say your square had a length of 10 and to find the area multiply the other side length since all squares mostly have the same side length multiply it by ten again and you get 100.
b) a^2 - 2
c) a^2 + 2a
d) a^2 + 2a - 2
