You are going to wash a large glass window in the shape of a trapezoid. The lengths of the bases of the window are 10 feet and 14 feet. The height is 8 feet. You can wash 6 square feet of the window in 1 minute. How long will it take you to wash the entire window?
+1223 First, we need to find the area of the trapezoid. (the average of the two bases multiplied by the height)
\(A = \frac{10 + 14}{2} \cdot 8 = 96\)
This area would take 96/6 = 16 minutes to wash.
