Answer:

Decimal form: 0.65
Step-by-step explanation:

To add, you need to get the denominators to be the same, so find the lowest number that both 4 and 5 fit into (multiplication):
4, 8, 12, 16, 20
5, 10, 15, 20
20 is the lowest common multiple of both. So multiply
by 5 (both top and bottom) and
by 4 (top and bottom) so that the denominators will have the same value:

Simplify

Now you can add the numerators. Keep the denominators the same:

This is the most simplified version.
The answer would be 18 because the formula for the area of a triangle is 1/2times base times height. So first you cut half of the base or the height then you times the base and height together.
ie base= 6 height=6
1.) cut half of either so you get 3
2.) then times them both 3 times 6 is 18
