## keana one year ago 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)?

1. keana

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

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

4. keana

ok.

5. keana

23750=47.5 (220 + b)

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

7. keana

okk

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

Find b

ok so you divide first?

yes

12. keana

280?
