Substitute numbers for area and height.
 
Put the area before the equals sign, and replace the letter h with the height.
 
...Multiply 1/2 by the height.
 
Calculate 1/2 x h/1 to get h/2. ...Isolate the b variable.
 
To isolate b, divide the entire equation by the number on the same side of the equation as b.
 
...Solve for b.
First, you must substitute numbers or letters for area and height. You put the area before the equal sign and replace the height with a letter/variable. Multiply the height by .5 (1/2). Then, solve for the base.
