the trapezoidal plot is 23,750 sq ft. If the top side is 220 ft and the height is 95ft, what is the bottom (B)?

OpenStudy (midhun.madhu1987):

Area of a trapezoid is given by: \[A = \frac{ 1 }{ 2 } h \times (b1 + b2)\] |dw:1441690822357:dw|

OpenStudy (midhun.madhu1987):

Here A = 23,750 , b1 = 220 , h = 95 find b2?

OpenStudy (keana):

ok.

OpenStudy (keana):

23750=47.5 (220 + b)

OpenStudy (midhun.madhu1987):

Good Job...Yup.. you need to solve it to get the answer

OpenStudy (keana):

okk

OpenStudy (midhun.madhu1987):

(220 + b) = 23750/47.5 (220 + b) = 500

OpenStudy (midhun.madhu1987):

Find b

OpenStudy (keana):

ok so you divide first?

OpenStudy (midhun.madhu1987):

yes

OpenStudy (keana):

280?
