The rectangles below are similar in shape. How wide is the smaller rectangle?

Amanda [17]

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

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