Part 1
Write the perimeter of the floor plan shown as an algebraic expression in x.
12
x - 12
3
?
x - 5

Answer 1

The perimeter of the floor plan shown as an algebraic expression in x is:

P = 4x - 8

To find the perimeter, you add up the lengths of all four sides.

Two sides have length x, and the other two sides have length x - 4.

So, the perimeter is:

P = x + x + (x - 4) + (x - 4)

P = 4x - 8

Therefore, the answer is P = 4x - 8.
