Determine polynomial expressions for the perimeter and the area of the figure shown below
help plz

Perimeter: 4x + 2
The perimeter is equal to 2 times the length plus 2 times the width.
2(x + 1) + 2(x)
2x + 2 + 2x
4x + 2
Area: x^2 + x
The area is equal to the length times the width.
(x + 1)(x)
x^2 + x
Hope this helps! :)
