Terms are the numbers and variables that are usually separated by an addition sign or a subtraction sign. In the expression 2x, 3y, 5z, and 4 are all terms.
Variables are the letters that come after a number. They represent the unknown number in the equation. The x, y, and z in the expression are the variables.
Coefficients are the numbers in front of the variables. For example, 2, 3, 5, and 4 are the coefficients.
The constants are the "signs" in between the terms. These include the addition sign and the subtraction sign.

Step-by-step explanation:
Base: 3 × 10 = 30
Rectangle Sides: 2.5 × 10 = 25 (×2 = 50)
Triangle Sides: 2 × 3 = 6 (÷2 ×2 = 6)
Add: 30 + 50 + 6 = 86
