Sally wants to paint a mural that covers a wall with an area of 1,440 square feet the height of the wall is 2/5 of it's length what is the length and the height of the length

show your work

Okay so you would do this:

1,440 sq feet

2/5 which you need to put in a decimal and it would turn out to be 0.4

You would need to divide.

0.4 / 1,440 = 2.7

You would get 1.08 and that should be your answer.

You would get 2.7

You would simplify and multiply 0.4 to 2.7.
