Zohar is using scissors to cut a rectangle with a length of 5x – 2 and a width of 3x + 1 out of a larger piece of paper. which expression can be used to find the perimeter of the rectangle and what is the perimeter if x = 4?

Answer with Step-by-step explanation:

Zohar cut a rectangle with a length of 5x – 2

and a width of 3x + 1

We know that:

Perimeter of rectangle is:

Perimeter=2(length+width)

                =2(5x-2+3x+1)

                =2(8x-1)

                =16x-2

Hence, expression which can be used to find the perimeter of the rectangle is:

16x-2

Now, when x=4

16x-2=16×4-2

        =62

Hence, when x=4 ,Perimeter=62

Step-by-step explanation:

Given: The length of the rectangle is and width of the rectangle is

To find: An expression that can be used to find the perimeter of the rectangle, and the perimeter when x is 4.

Solution:

Here, Length is given as

width of the rectangle is

Let P represents the perimeter of the rectangle

We know that perimeter of a rectangle is

So, we have

Therefore, the expression to find the perimeter is

Now, we need to find the perimeter at

On substituting  in we have,

Hence, the perimeter is 62 units when x is 4.
