Well, you want to solve for a. You first add the 4 to both sides.
3a-4<5
3a<9
Then you want to get a by itself so you divide both sides by 3. Since the 3 is positive you don't have to worry about switching the sign. It stays this way <
After you divided both sides by 3 you get a<3
Trapezoid Area = (Bases / 2) * Height
20 cm² = 5 * Height
Height = 4 cm
