Ex.Misc. Q.8

Find the area of the triangle formed by the lines y – x = 0, x + y = 0 and x – k = 0.

The equations of the given lines are

y – x = 0 .............. (1)

x + y = 0 .............. (2)

x – k = 0 .............. (3)

The point of intersection of lines (1) and (2) is given by

x = 0 and y = 0

The point of intersection of lines (2) and (3) is given by

x = k and y = –k

The point of intersection of lines (1) and (3) is given by

x = k and y = k

Thus, the vertices of the triangle formed by the three given lines are (0, 0), (k, –k), and (k, k).

We know that the area of a triangle whose vertices are (x₁, y₁), (x₂, y₂), and (x₃, y₃) is

(1 ÷ 2) |x₁(y₂ – y₃) + x₂(y₃ – y₁) + x₃(y₁ – y₂) |

Therefore, area of the triangle formed by the three given lines

= (1 ÷ 2) |0(-k – k) + k (k – 0) + k (0 + k) |

= (1 ÷ 2) |k² + k²|

= (1 ÷ 2) |2k²|

= k² square units
