The ratio that would be used to find the value of the side of the rectangle, is: A. 2.1/6.3 = 8.7/x.
What are Similar Rectangles?
Similar rectangles are rectangles that have corresponding sides that have the same ratio and are proportional to each other.
Given that the two rectangles are similar, the ratio of their corresponding sides would be equal.
Therefore, if we make x to represent the missing side of the rectangle, we would have the following ratio:
2.1/6.3 = 8.7/x
Therefore, the ratio that would be used to find the value of the side of the rectangle, is: A. 2.1/6.3 = 8.7/x.
