Proprtional triangles    so

47/82 = x/73.8

x= 42.3 m

I don't believe my work is correct but I got 12.7 meters squared hoe that helps.

Hope not hoe sorry 😅😇😀

Well here's how you work it out

X/47 = 82.8/92 (This is set up like a proportion)

So 92*x=92 and 82.8*47= 3891.6

You would divide 92 by 3891.6

and x= 42.3m

Thanks, Isabelle and EP.......here's one more way of looking at it

Each side of the smaller triangle is 9/10 of its respective side in the larger triangle

So   47 (9/10)  = 42.3m
