Ineed with these two word problems about polynomials. and you!

49)  check the first picture below

the actual width of the width will then be x + 20 + x or, 20+2x
and the actual length will then be x + 22 + x , or 22 + 2x

recall for a rectangle, Area = length * width
thus   A = (22+2x)(20+2x)     <-- FOIL it if you wish, to simplify

------------------------------------------------------------------
50)  check the 2nd picture included
so the actual length is (40+x), whilst the width is (20+2x)

A = (40+x)(20+2x)

same FOIL it if you want and simplify

The first option would be correct if it were one half and not one
