Step-by-step explanation:
The ratio of the area of the triangles can be calculated as following:

Where
is the lenght of the given side of the smaller triangle and
is the lenght of the given side of the larger triangle.
Therefore:

It can be written as following:

The ratio of the perimeter is:

Where
is the lenght of the given side of the smaller triangle and
is the lenght of the given side of the larger triangle.
Therefore:

It can be written as following:

The common denominator would be 18. So, 5/6 becomes 15/18 and 7/9 becomes 14/18
