a cistern 5 m long and 2 m wide contains water up to a breadth of 1 m 10 cm . find the total area of the wet surface .
"explanation : area of the wet surface = 2 [ lb + bh + hl ] - lb = 2 [ bh + hl ] + lb = 2 [ ( 2 * 1.1 + 5 * 1.1 ) ] + 5 * 2 = 25 m square option c"
add(multiply(const_2, add(multiply(add(divide(10, const_100), 1), 2), multiply(add(divide(10, const_100), 1), 5))), multiply(2, 5))
