Question

Leo wants to paint a mural that covers a wall with an area of 1440 square feet. the height of the wall is 2/5 of its length what is the length and the height of the wall?

Answer 1

`A=lh=1440\\h= (2)/(5)l\\1440=l( (2)/(5)l)\\1440=(2)/(5) l^(2)\\3600=l^(2)\\60=l\\\\h= (2)/(5)(60)\\h=24`

H = 24 feet
L = 60 feet
