Question

Write an expression for the perimeter of a rectangle with Length l = 2x + 3 and width w = x – 2

Answer 1

Step-by-step explanation:

The perimeter of a shape is the length around the edges.  For a rectangle with length L and width W:

P = 2L + 2W

Given L = 2x + 3 and W = x – 2, we can substitute:

P = 2(2x + 3) + 2(x – 2)

P = 4x + 6 + 2x – 4

P = 6x + 2

Answer 2

Answer:

P=6x+2

Step-by-step explanation:

The perimeter of a rectangle is given by P= 2L + 2W

L=2x+3

W=x-2

Substituting with the values in the question we get:

P= 2(2x+3) + 2(x-2)

Open the brackets and then add the results.

=4x+6+2x-4

=6x+2

Therefore perimeter of the rectangle is given by the expression.

P=6x+2
