Question

Leo wants to paint a mural that covers a wall with an area of 300 square feet. The height of the wall is 1/3 of its length. What is the length and the height of the wall?

Answer 1

30*10

Explanation:

Answer 2

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
