Farmer and certified math idiot here.

I’ve got a field that is shaped like a trapezoid. The length down the center of the field is 470’. The width at one end is 340’, and the width at the other end is 30’. I’m planting my crop on a 10’x10’ grid. I need to know how many plants I can plant. Thanks.

Ps let me know if you need more info. Hopefully that’s enough.

. You will require 86950/100 = 869.5 plants.

Edit what are you planting, trees ?

Without checking your math, Flum, I think you're telling him 869.5 grids, not plants.

The area of a trapezoid is = 0.5(b1+b2)h = 0.5 (340 + 30) 470 = 86950 square feet. If you are using 1 plant per 10x10 = 100 square feet. You will require 86950/100 = 869.5 plants.

Does that sound about right

Edit what are you planting, trees ?

Yes that sounds about right. But I’m not sure.

But maybe that wasn't his question.  Given the shape of his field, he couldn't get that many and have them all be 10 x 10.

Could someone please confirm if that’s 869 grids or plants? I’m just trying to get a ballpark figure. No field is perfectly straight or symmetrical. Plus, with all my other fields I’ve already got more crop than I can handle.

I appreciate it guys!
