The algebraic expression that will represent the perimeter in centimeters of the given rectangle is:
<em><u>Recall:</u></em>
Perimeter of a rectangle = 2(L + W)
<em>Given the following dimension of a </em><em>rectangle</em><em>:</em>
- width (W) = (8.4x + 2.2) cm
- length (L) = (4.5x + 3.4) cm
To find the expression that represents the perimeter, plug in the given values into the formula for perimeter.
- Thus:
Perimeter =
- Open the bracket
Perimeter =
- Add like terms together
Perimeter =
