When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
If a = 1, b = 6, c = 2, and d = 9, what is the perimeter of this quadrilateral?
| 22 | |
| 18 | |
| 21 | |
| 26 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 1 + 6 + 2 + 9
p = 18
