Question

rectangle o is a scaled copy of rectangle n. what is the value of m?

Explanation:

Step1: Set up proportion

Since the rectangles are scaled - copies, the ratios of corresponding sides are equal. So, $\frac{4}{5.4}=\frac{2.8}{m}$.

Step2: Cross - multiply

Cross - multiplying gives us $4m = 2.8\times5.4$.

Step3: Calculate the right - hand side

$2.8\times5.4 = 15.12$, so $4m=15.12$.

Step4: Solve for m

Dividing both sides by 4, we get $m=\frac{15.12}{4}=3.78$.

Answer:

$3.78$
