Answer:
Base (x) = 2
Explanation:
First we know that to find the area you do:
Area=Base x Height
So plug in the 22 as the area and the 11 as the height so it looks like this:
22 = (x) x 11
Then to find x all you have to do is divide 22 by 11 in order to get x by itself:
22/11 = x
So your answer is 2
