Image attached! these triangles are similar. find the area of the smaller triangle to the nearest whole number.

As the triangles are similar, the ratio of their length and area will be the same
so as the ratio of the length is
16:12=4:3
the ratio of the area is also 4:3
we know the bigger triangle area is 105.
So 105 would be 4 units.
1 unit would be 26.25
and 3 units would be 78.75
rounded up to 79
