Step-by-step explanation:
Given
Rectangle A:


Required
Determine the possible dimensions of Rectangle B
<em>The question has missing options; however, the question can still be solved.</em>
<em></em>
Rectangle B being an enlarged copy of A implies that the dimension of A A is enlarged in equal proportion to form B
Take for instance, the measurements of Rectangle B are


Divide the corresponding lengths of B by A to get the enlargement ratio

For length:


For width


Notice that both ratios are the same.
For this measurement of B, we can conclude that B is an enlargement of A
Assume another measurements for B


Calculate Ratios

For length:


For width


Notice that, both ratios are not equal.
For this measurement of B, we can conclude that B is not an enlargement of A
<em>Conclusively, all you have to do is: determine the ratios of the dimensions of B to A, if the result are equal then B is an enlarged copy of A; if otherwise, then B is not an enlarged copy</em>
