A reservoir is 90m long and its cross section is an isosceles trapezoid having equal sides of 11m, an upper base of 17m, and a lower base of 5m. At the instant when the water is 5m deep, find the rate at which the water is leaking out if the water level is falling at 0.1m/hr. (Volume of a a+b trapezoidal prism is ºhl. 2 Note: a and b = are bases of the trapezoid h = is the height of the trapezoid |= is the length of the prism
