Question

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

Answer 1

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! :)
