Question

Calculate NL if a=25, b=27.73, and c=12

Answer 1

NL=10.82

Explanation:

Start by finding the area of the triangle. We do this by using c as the base.

1/2bh=1/2(12)(25)=150

Now that we know the area is 150, we turn the triangle so b is the base and use the formula again. This time we’re looking for the height, which is NL.

1/2bh=

1/2(27.73)h=150

13.865h=150

h=10.8186

Rounded to the nearest hundredth, it’s NL=10.82
