A rectangle has a length (x + 6) m and a width of 7 m. Find expressions to represent the perimeter and
area of the rectangle. Complete the explanation of how you determined your answers.
The perimeter is ( x+ )m, and the area is ( x + ) m^2. I (added or multiplied) the length
and width together and doubled the (sum or product) to find the perimeter. I (added or multiplied)
the length and width to find the area.

The perimeter is the sum of the sides

p = (x+6) + 7 + (x+6) + 7

Answer: Perimeter p = 2x + 26

The area is the product of two perpendicular sides,

A = 7(x+6)

Answer: Area A= 7x + 42

Explanation:

The perimeter is   2x + 26 m, and the area is 7x + 42 m^2. I added the length  and width together and doubled the sum to find the perimeter. I multiplied  the length and width to find the area.

Answer: Perimeter= (2x+26)m

Area= 7x+42m^2

Step-by-step explanation:

Length= (x+6)m

Width= 7m

Perimeter of a rectangle= 2(length+width) = 2(x+6+7)m

= 2(x+13)m = (2x+26)m

Area= length x width

= (x+6) × 7

= (7x+42)m^2

I added the length and width together and doubled the sum.

I multiplied the length and width to find the area
