Answer:

\huge\boxed{x=28\ ft}

Step-by-step explanation:

If two rectangles are similar, then corresponding sides are in proportion.

Therefore we have the equation:

\dfrac{x}{42}=\dfrac{36}{54}

cross multiply

54x=(42)(36)\\\\54x=1512

divide both sides by 54

\dfrac{54x}{54}=\dfrac{15212}{54}\\\\x=28
