State of the triangles in each pair are similar. If so State how you know whether they are similar and complete the similarity statement.

not similar

We don't have to work anything out, just look through the answers.   There are no angle measures or angle congruences indicated so none of the similarity theorems that use angles, namely SAS and AA, can be right.  That leaves not similar.

If we did want to check SSS similarity we have to check the corresponding ratios are equal.  Compare for example the ratio of the smallest sides to the ratio of the medium sides,

62/7 to 81/8

We can see those aren't equal because 8×62 is even and 7×81 is odd.

y= -

the answer is 48m^2!
