Quandaries
and Queries 

I'm working on an Algebra 2 problem from my text. I'm going into tenth grade and I have a triangle who's sides measure 3ft, 4ft, and 5ft. I need to find the area however I don't know the height, or how to get it. If you could send me the formula that would be fantastic. Thanks so much for your help! Barkie 

Hi Barkie, The short answer is that a triangle whose sides are 3, 4, 5 is a right triangle with legs 3 and 4  it's area is 1/2(3*4) = 6. This is true since
In general, for the area of a triangle given the sides a, b, and c, one would use Heron's formula for the area: First compute the semiperimeter
Then
