Answer 1

Answer/Step-by-step explanation:

Length of rectangle =
`l`

Width of rectangle =
`(1)/(3) of l - 1 = (1)/(3)l - 1 = (l)/(3) - 1`

A. Expression for finding area of the rectangle:

Area of rectangle is given as
`length*width`

`Area = l((l)/(3) - 1)`

Or

`Area = l*(l)/(3) - l*1`

`Area = (l^2)/(3) - l`

b. Expression for finding perimeter:

Perimeter of rectangle is given as
`2(Length + Width)`

`Perimeter = 2(l + ((l)/(3) - 1))`

Or

`Perimeter = 2(l) + 2((l)/(3) - 1)`

`Perimeter = 2l + (2l)/(3) - 2)`

c. Quotient of Perimeter divided by area:

`2(l + ((l)/(3) - 1))` ÷
`l((l)/(3) - 1)`

`2(l + ((l)/(3) - 1))` ÷
`(l^2 - 3l)/(3)`

Change the ÷ to × and flip the fraction on your right upside down.

`2(l + ((l)/(3) - 1)) * (3)/(l^2 - 3l)`

`2l + 2((l)/(3) - 1) * (3)/(l^2 - 3l)`
