Straight LineHard
Question
Area of the parallelogram formed by the lines y = mx, y = mx +1, y = nx and y = nx +1 equals
Options
A.
B.
C.
D.
Solution
Let lines OB : y = mx
CA: y = mx + 1
BA: y = nx + 1
and OC : y = nx
The point of intersection B of
OB and AB has x coordinate
Now, area of a parallelogram
OBAC = 2 × EA OF ᐃOBA
depending upon whether m > n or m < n
