Rectangle EFGH is similar to rectangle JKLM. Which proportion can be used to find the value of x?

A.2/12=5/x B.5/2=x\12 C.5/12=2/x D.12/5=2/x

*See attached picture for the diagrams being referred to

C. ⁵/12= ²/x

Step-by-step Explanation:

Given that rectangle EFGH is similar to rectangle JKLM, it means the corresponding sides of both rectangles are similar, and as such the ratios if the corresponding sides of rectangle EFGH and rectangle JKLM would be equal.

Thus, EF/JK = FG/KL

Since, EF = 5; JK = 12; FG = 2; and KL= x, therefore, the proportion to use in finding x would be:

⁵/12= ²/x
