Answer:
Step-by-step explanation:
3x and 3y are not "like terms," despite having the same coefficient.
Like terms have the same variable. For example, 3x and 2x are like terms, so
3x+2x = 5x
we know that two similar triangles will have ratio corresponding side is same.
ratio triangle 1 is 75m^2.
and triangle 2 is 12m^2.

so we have ratio of area
.
ratio of perimeter will be
.
from these perimeter ratio also
.
