Question

1 if these two rectangles are similar, what is the measure of the missing length d? note: figures not drawn to scale. d = millimeter.

Explanation:

Step1: Set up proportion

Since the rectangles are similar, the ratios of corresponding sides are equal. So, $\frac{2}{4}=\frac{d}{2}$.

Step2: Cross - multiply

Cross - multiplying gives $4d = 2\times2$.

Step3: Solve for d

$4d=4$, then $d = 1$.

Answer:

$1$
