138.6=2(h+b) divide both sides by 2 69.3=h+b suub (8/3)b for h 69.3=(8/3)b+b times both sides by 3 to get rid of fraction 207.9=8b+3b 207.9=11b divide both sides by 11 18.9=b
sub back
(8/3)b=h (8/3)18.9=h 50.4=h
area=height times base aera=50.4 times 18.9 aera=952.56 cm²
1. base=18.9 cm 2. height=50.4 cm 3. area=952.56 cm²
A positive correlation is a relationship between two variables in which both variables move in the same direction. Ex: Higher levels of one variable are associated with higher levels of the other.
