Question

the two rectangles are scale drawings. what is the measurement of x?
20 units
24 units
4 units
1,25 units

Explanation:

Step1: Set up proportion for scale drawings

Since the rectangles are scale drawings, their corresponding sides are proportional. So, $\frac{5}{7}=\frac{x}{28}$.

Step2: Solve for x using cross - multiplication

Cross - multiplying gives $7x = 5\times28$. First, calculate $5\times28 = 140$. Then, divide both sides by 7: $x=\frac{140}{7}=20$.

Answer:

20 units
