Answer 1

The formula for the area of a triangle is A=1/2bh.
This means that one half of the base times height is the area of the triangle.
since you don't the height, fill in the info that you do know:

45.5=1/2(10)h
or
45.5=5h

Now, you should have no problem solving for h :)

Answer 2

answer is 9.1 m
