Question

I need help with steps on how to solve and how to get the answer

Answer 1

two rectangles to be similar, their sides have to be proportional (form equal ratios). The ratio of the length should equal the ratio of the width.

thus,

`\begin{gathered} (12)/(x)=(6)/(10) \\ 12\cdot10=6x \\ 120=6x \\ x=(120)/(6) \\ x=20 \end{gathered}`

Therefore x=20.
