Every cross section of a drainage is an isosceles trapezoid with a small base of 3 feet and a height of 1 foot. Determine the width of the larger base that would give the ditch a cross-sectional area of 5ft^2.
\n" ); document.write( "--------------
\n" ); document.write( "Area = (h/2)(b1+b2)
\n" ); document.write( "---
\n" ); document.write( "5 = (1/2)(3+b2)
\n" ); document.write( "10 = 3+b2
\n" ); document.write( "b2 = 7 ft
