    ANSWER

    4x−3y+4=0

    ⟹x=

    4

    −4+3y

    Let, y=4, then x=

    4

    −4+3(4)

    =2

    Similarly, when y=0,x=−1

    4x+3y−20=0

    ⟹x=

    4

    20−3y

    Let, y=4, then x=

    4

    20−3(4)

    =2

    Similarly, when y=0,x=5

    Plotting the above points on the graph, we get, the intersecting point i.e(2,4)

    Area of the region bounded by these lines and x-axis =

    2

    ×6units×4 units

    =12 sq. units.
