Answer:
the top right box
Step-by-step explanation:
Area of a triangle = 1/2 x base x height
using the given information: area = 40 and base = 20
you now have 40 = 1/2 x 20 x height
divide both sides by 1/2
80 = 20 x height
divide both sides by 20
height = 80 / 20
height = 4 in.
I used a triangle generator, see picture attached
8/36 because:
8+16+12=36
and if you simplify it the answer will be 4/18 2/9
The answer should have been 8.6 that was wrong but it is okay you were close
