Need help with my geometry

   / Need help with my geometry #11  
This is fun. I'm anxiously awaiting the debate toward the end result, which is of course, the correct answer.

So far we have 4 different answers. :D

About 1/100 acre, in round numbers. :)

I thank everyone for their help. I was getting so many different answers I had to try to figure it out without using math. I drew it on a piece of paper, cut out the 2 sides, placed them together into a square and measured it.
My answer is 440 square feet.

I hope I am right because I am figuring out how much concrete I need to pour my driveway apron.

That sounds right to me.

And for some strange reason, when I saw this I had concrete in mind. Go figure..... :)

The distance between the two straight lines is 21.8 sqrt (24^2 - 10^2). So 21.8 x 20 = 438.

I'd go with 480 for concrete, I'd rather leave some on the truck than be short.

You're close enough! Dieselcrawer is dead on - 436.35 sq. ft. Your 22' dimension is actual 21.8 feet.

So far I'm thinking Greg and Eric are the closest. Anxious to hear their mathematical method of getting that answer. :)

It's been so long since I got out of school, I can't remember how to solve this problem.
I can't even remember if its geometry, trigonometry or whatever. Maybe its early Alzheimer's?
Please help me find out how many square feet this is.
