If the area of triangle ABC is 60 square units and the base is 12 units, what is the height? (2019)
Step 1: Write down the formula for the area of a triangle: Area = 1/2 * base * height.
Step 2: Substitute the known values into the formula. We know the area is 60 square units and the base is 12 units, so we write: 60 = 1/2 * 12 * height.
Step 3: Simplify the right side of the equation. Calculate 1/2 * 12, which equals 6. Now the equation is: 60 = 6 * height.
Step 4: To find the height, divide both sides of the equation by 6. So, height = 60 / 6.
Step 5: Calculate 60 divided by 6, which equals 10. Therefore, the height is 10 units.
Area of a Triangle – The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.
Algebraic Manipulation – The ability to rearrange equations to solve for an unknown variable, in this case, height.
