Question

2x+y=2
2y-x=4
what is the area of ∆so formed by the two lines and the line y=0

{solve it step by step}​

Answer 1

Answer:

Point of intersection = A0,2.So

2x + y = 2 and

2y - x= 4

BC=5 units and

OA=2 units

ar∆ABC=12×BC×OA=12×5×2=5 square units

Answer 2

Answer:

Point of intersection = A0

=>2x+y = 2

=>2y-x = 4

BC = 5units and

OA = 2 units
