The area of the triangle formed by the lines y = x, x = 6 and y = 0 is
Given:
Equation 1: y = x Equation 2: x = 6 Equation 3: y = 0
According to the given question Equation 1 , 2 & 3 cuts each other at three different points creating a triangle and we need to calculate the area of this triangle formed by these lines.
Now Equation 2 is a line parallel to Y axis at a distance of 6 units. Equation 3 is the equation of the x axis.
So we can say that equation 2 & 3 are mutually perpendicular to each other and the triangle formed by these 3 equations is a right angled triangle .
We solve equation 1 & 2 by substitution method
After solving we get x = 6 & y = 6
So the perpendicular height of the triangle turns out to be 6 units.
Since Equation 2 is at a distance of 6 units from the origin so the length of the base turns out to be 6 units.
Perpendicular height = 6 units
Base Length = 6 units.
Area of the Triangle = * (perpendicular length) * (base length)
Area of the triangle becomes = * 6 *6 = 18 sq.units
The Area of the triangle is 18 sq. units
