the area of a parallelogram form by the lines 4Y - 3 x is equal to 1, 4 Y - 3 x minus 3 equal to zero, 3 Y - 4 x + 1 equal to zero, 3 Y - 4 x + 2 equal to zero is

Express each line in the form y=mx+c..Then u will come to know that 2 of them will have same value of m. Let`s say first 2 of them have y intercept(c) c1 and c2 and the other 2 be d1 and d2.call the slopes as m1 and m2 . m1 corresponds to the ordinates c1 and c2 & m2 corresponds to d1 and d2......Now use the formula..MOD|(c1 - c2)(d1 - d2)|divided by|(m1 - m2)|
