__Math Tutoring on ____Area Application Problems Involving Equations in One Variable__

** **

**Area** formulas for plane figures used in math tutoring are:

1.** ****Triangle** : Area = ½ × b × h, b = base, h = vertical height

2. **Square** : Area = a^{2}, ^{ }a = length of side

3.** ****Rectangle** : Area = w × h, w = width, h = height

4. **Parallelogram** : Area = b × h, b = base, h = vertical height

5.** Trapezoid** : Area = ½(a+b) × h, h = vertical height

6. ** ****Circle **: Area = π × r^{2} , Circumference = 2 × π × r, r = radius

7. ** ****Ellipse** : Area = πab

8. **Sector** : Area = ½ × r^{2} × θ , r = radius, θ = angle in radians.
