Answer 1

Answer:

12 sq units

Step-by-step explanation:

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
