Question

Is the 72 or right or nah this is way to confusing for me

Answer 1

36mm2

Explanation:

The ratio between sides is:

`(12)/(8)`

Since this is the proportional area, we square this ratio

`((12)/(8) )^(2)=(12^(2) )/(8^(2) )= (144)/(64) =2.25`

If the minor triangle has an area of 16 mm2, then the greater triangle will have an area of:

`16(2.25)=36mm^(2)`

Hope this helps
