Math Problem Statement

Solve the formula for h .

Area of a triangle: A=1/2bh

Solution

To solve the formula for hh, we'll start with the formula for the area of a triangle:

A=12bhA = \frac{1}{2}bh

Where:

  • AA is the area,
  • bb is the base,
  • hh is the height.

Now, let's solve for hh:

  1. Multiply both sides by 2 to eliminate the fraction:

2A=bh2A = bh

  1. Divide both sides by bb to isolate hh:

h=2Abh = \frac{2A}{b}

Thus, the height hh is:

h=2Abh = \frac{2A}{b}

Let me know if you'd like more details or have any questions!


Here are 5 related questions to consider:

  1. What is the area of a triangle if the base is 10 and height is 5?
  2. How would you solve for the base bb instead of the height?
  3. If the area is 50 and the base is 8, what is the height of the triangle?
  4. How would the formula change for a right-angled triangle?
  5. How is the area of a parallelogram related to this formula?

Tip: Always remember to use the same units for base and height when calculating the area!
