Question

rectangle a is 12 centimeters by 3 centimeters. rectangle b is a scaled copy of rectangle a. select all the pairs that could be the dimensions of rectangle b. 6 centimeters by 1.5 centimeters 10 centimeters by 1 centimeter 18 centimeters by 4.5 centimeters 6 centimeters by 1 centimeter 80 centimeters by 20 centimeters

Explanation:

Step1: Find the ratio of sides of rectangle A

The ratio of length to width of rectangle A is $\frac{12}{3}=4$. For rectangle B (a scaled - copy of A), the ratio of its length to width should also be 4.

Step2: Check each pair

Pair 1: 6 centimeters by 1.5 centimeters

The ratio is $\frac{6}{1.5}=4$.

Pair 2: 10 centimeters by 1 centimeter

The ratio is $\frac{10}{1}=10
eq4$.

Pair 3: 18 centimeters by 4.5 centimeters

The ratio is $\frac{18}{4.5}=4$.

Pair 4: 6 centimeters by 1 centimeter

The ratio is $\frac{6}{1}=6
eq4$.

Pair 5: 80 centimeters by 20 centimeters

The ratio is $\frac{80}{20}=4$.

Answer:

6 centimeters by 1.5 centimeters, 18 centimeters by 4.5 centimeters, 80 centimeters by 20 centimeters
