So our original length (a) is 3, and our original width (b) is 2:

a = 3

b = 2

We increase both by x, so our new length (a_{2}) is 3 + x and original width (b_{2}) is 2 + x:

a_{2} = 3 + x

b_{2} = 2 + x

To find our new area, we multiply the length and width:

a_{2} * b2 = **(3 + x)(2 + x)**

If your teacher wants you to distribute your answers, you'd just go ahead and do so and your final answer would be **x**^{2}** + 5x + 6**.
