A cistern 12 m long and 14 m wide contains water up to a depth of 1 m 25 cm. The total area of the wet surface is:  Choose the correct option.
A) 224 m2 B) 250 m2 C) 220 m2 D) 230 m2 E) 233 m2
Area of the wet surface	= [2(lb + bh + lh) - lb]   = 2(bh + lh) + lb   = [2 (14 x 1.25 + 12 x 1.25) + 12 x 14] m2   = 233 m2.   answer :233 m2
