Answer this: Missouri has a shape that is similar to a trapezoid with bases 198 miles and 276 miles and a height of about 270 miles estimate

Question

It's an estimation and I just don't get it... Help!

Answer 1

Area of Trapezoid = (1/2)(sum of bases)(height)

 

                         = (1/2)(198+276)(270)

 

                         = (1/2)(474)(270)

 

                         = 63,990 miles²
