How Do You Find the Height of a Triangle if You Know the Area and Base?

The area of a triangle is 32.4 cm2 and the base is 7.2 cm. Find the height.

Summary

  1. A, b, and h are variables
  2. A stands for the area
  3. b stands for the length of the base
  4. h represents height, which is what we're looking for

Notes

    1. The formula for the area of a triangle is A = (1/2)bh
    2. A is the area
    3. b is the length of the base
    4. h is the height of the triangle
    1. A is the area, which is 32.4
    2. b is the length of the base, which is 7.2
    3. h is the height of the triangle, which is what we're trying to find
    1. When we plug what we know into the formula, we're left with an equation with just one variable, h
    1. First multiply 7.2 by 1/2, which is the same as dividing by 2
    2. Then divide by 3.6 on both sides to get h by itself
    1. Put 9 in for h in the original formula to see if we get the area we were supposed to get
