Question

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

Answer 1

Answer:

36mm2

Step-by-step explanation:

The ratio between sides is:

$\frac{12}{8}$

Since this is the proportional area, we square this ratio

$(\frac{12}{8} )^{2}=\frac{12^{2} }{8^{2} }= \frac{144}{64} =2.25$

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
