15/6=2.5 which is the scale factor since they are similar triangles. We divide each side of the large triangle by 2.5 to get the sides for the small triangle since they are similar. 20/2.5=8cm
25/2.5=10cm

For the second problem, you put 15/6 and set in equal to x/8 when you cross multiply you get 6x=120 then you divide x=20

For the last problem, you divide 43,75 by 5 then multiply it by 400 to get the kiloliters which equals 3,500.

Bogdan [553]
Age of two trees=162
162÷3=54
The age of one tree is 54
The age of other tree is 54 +54 which is equal to 108.
So let's just check if this statement is true or not. 54+108=162
Hence the answer is true
