The gcf of 18 and 20 is 2, so your answer is:
2(9+10)
Rational ! the number doesn't repeat forever or anything like that. it simplifies nicely.
You find the area of a triangle by using 1/2*b*h where b is the base and h is the height. since we already know the area is 20 and the height is for you plus them in so the problem would be 20= 1/2 (b) (4) then you multiply what you know together to get 20= 2b and then isolate the b by dividing both sides by two so the base should be 10 m
A) triangle c, has the largest area
b) a= 1/2 (3) (3) a= 4.5
