sketch a picture?
total length of field = length of rectangle + 2 radii
width of field = 2 radii
you were given A ... solve for r.
I'm having a hard time with this problem
A grass field is shaped like a rectangle with semicircles on both ends. The total length of the field is exactly 100 feet. How wide, to the nearest tenth of a foot, should the field be if its total area is 4,000 square feet?
Can I assume the radius of the circle is 1/2 of the width of the rectangle?
And I still am not seeing how I could solve this
