Question

if these two shapes are similar, what is the measure of the missing length u? u = centimeters. not feeling ready yet? these can help: work it out

Explanation:

Step1: Set up proportion

For similar - shaped parallelograms, the ratios of corresponding sides are equal. Let the ratio of the sides of the two parallelograms be $\frac{u}{2}=\frac{2}{1}$.

Step2: Solve for u

Cross - multiply the proportion: $u\times1 = 2\times2$. So, $u = 4$.

Answer:

4
