Question

the width of a rectangle is x centimetres and its length is (x+ 2) cm. Write down an expression for the perimeter of the rectangle, giving your answer in its simplest form

Answer 1

Answer:  P = 4(x + 1)

Step-by-step explanation:

Answer 2

Perimeter = length + length + width + width

P= (x + 2) + (x + 2) + x + x
P = x + 2 + x + 2 x + x
P= 4x + 4

Some teachers then want you to pull out the common factor of 4. If yours does, it’s P = 4(x + 1)
