determine the perpendicular distance between the parallel limes y = mx and y = mx + 1
and determine the inersection sets (i.e. the coordinates of the points of intersection) of lines y = nx +1 with y = mx and y = nx with y = mx .
u get two points as (0,0) and [(1 / (m-n)), (m / (m-n))]
determine the distance between the two points
and then the area is given by
base * altitude :)
and u will get the required answer :)
