The lines are
x-axis : y = 0
y-axis : x = 0
x + y = 6
or, x/6 + y/6 = 1
So, this line intersects the x-axis at (6,0) and the y-axis at (0,6).
We get a triangle according as the given attachment.
The base of the triangle is 6 units and its height is also 6 units.
Therefore, the area of the triangle be
= 1/2 × base × height
= 1/2 × 6 × 6 unit²
= 3 × 6 unit²
= 18 unit²
