The length of a rectangle is 6 inches longer than it’s width. the perimeter of the rectangle is 36 inches long. how long and how wide is the rectangle.

Length of rectangle = 12 inches

Width of rectangle = 6 inches

Step-by-step explanation:

Let the width of rectangle in inches be =

Given: The length of rectangle is 6 inches longer than its width.

So, length of rectangle in inches

Perimeter of a rectangle is =

Plugging in in the perimeter formula.

Perimeter of rectangle in terms of width =  

Simplifying and using distribution.

⇒

⇒

⇒

We are given perimeter of rectangle = 36 inches.

So, we can equate to find

Subtracting both sides by 12.

Dividing both sides by 4.

inches

Using to find

inches

Length of rectangle = 12 inches

Width of rectangle = 6 inches

all it means is function 3

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
