Question

Rectangle A has side lengths of \[6\text{ cm}\] and \[3.5\text{ cm}\]. The side lengths of rectangle B are proportional to the side lengths of rectangle A. What could be the side lengths of rectangle B? Choose 2 answers: Choose 2 answers:

Answer 1

The side lengths of rectangle B (x and y) could be in the ratio of 7:12.

The side length of B divided by the side length of A is a constant. Let's denote the side lengths of rectangle B as x and y. The ratio becomes:

(x / 6) = (y / 3.5)

Now, cross-multiply to solve for x and y:

3.5x = 6y

Solving for y in terms of x:

y = (3.5x / 6)

Simplifying the fraction:

y = (7x / 12)

Hence, the side lengths of rectangle B (x and y) could be in the ratio of 7:12.
