Answer: 84 1/2 or 84.5 same thing
Explanation:
It says the base is half the height and the height is 6 1/2. So you do 6 1/2 x 2 to get the height. And 6 1/2 x 2 = 13. The you do base x height so it would be 6 1/2 x 13. You have to make a mixed number so 6 1/2 as a mixed number is 13/2. When you have a whole number and your mutilpling with a fraction you put a one under it so 13 wwould turn into 13/1. Then you do 13/2 and 13/1 which equals 169/2. Next you divide 169 divided by 2 and that equals 84 remander 1. So the answer would be 84 1/2 or 84.5
