If I'm understanding this correctly 20 rounded to the nearest ten would be 20
1. D
2. A
3. C
Question 2 MIGHT be D, but I think it's A
1)find the area of a triangle. Multiply it by 2 or 4 depending on if they are the same size
2)find the area of the base
3)find the area of the other two sides if you haven’t already.
4) add them all together
as a decimal it would be 11.5
and as a fraction it would be 23/2
so none of those answers?
