how do you find the height of a triangle when all you have is the base, length and area?frown

area = (1/2) * base * height

 

For example....if we know that    base = 5    and   area = 10 sq units,    then

 

10 = (1/2) * 5 * height

10 = 5/2 * height

 

Multiply both sides of the equation by 2/5 .

10 * 2/5 = height

4 = height

Also....you can say

a = (1/2)bh          , where a is area, b is base, and h is height

 

Divide both sides of this equation by b

a/b = (1/2)h

 

Multiply both sides of this equation by 2.

2a/b = h

 

Now you can just plug in what you know for "a" and "b" and and solve for h smiley

10 = (1/2) * 5 * height
10 = 5/2 * height
 
Multiply both sides of the equation by 2/5.
10 * 2/5 = height
4 = height
