Question

PLEASE HELP, I DONT UNDERSTAND THIS.....Michael is laying carpet in a perfectly rectangular hall. The area of the hall is 240 square feet, and the width of the hall is 6 feet. How long is the hall?

Answer 1

l=a/w

Explanation:

Length equals area divided by width.

Answer 2

40 feet

Explanation:

We know that the area of a rectangle is represented as
`lw=a`, where l is the length and w is the width.

We already know the width, and we know the area, so we can plug these values into the equation.

`l\cdot 6 = 240`

Our goal is to now isolate the variable l, and to do this we can divide both sides by 6.

`(l\cdot6) /6 = 240/6\\\\l = 40`

Hope this helped!
