Answer:

Length = 30

Height = 10

Explanation:

Formula for the area = height * length. We know that the height of the wall is 1/3 of its length. This gives us another formula which is
h=(1)/(3) l

Now substitute this into the formula, while knowing that the area is 300.

So we have 300 =
(1)/(3)l * l

Solving for l gives us 30 and then substituting it back into the equation

h = (1)/(3) l , will give us that the height is 10.

Hope this helps
