Question from Karen:

if I have a triangle that measures 78 ft x 54 ft x 50 ft, how do I figure out what part of an acre that is??

Hi Karen,

Since you know the lengths of the sides of the triangle you can use Heron's Formula to find its area. I got 1,340 square feet. (You should check my arithmetic.) Now you need a conversion from square feet to acres. You can use a reference book but I prefer using the internet. I could type what is 1340 square feet in acres? into the Google search window but I'm a Mac user so I would just say Hey Siri, what's one thousand three hundred and forty square feet in acres?

I hope this helps,
