Answer:
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Simplifying
n + -16 = m
Reorder the terms:
-16 + n = m
Solving
-16 + n = m
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '16' to each side of the equation.
-16 + 16 + n = 16 + m
Combine like terms: -16 + 16 = 0
0 + n = 16 + m
n = 16 + m
Simplifying
n = 16 + m
Number 1 would be the correct answer :)
