What is the area (in sq. units) of the triangle formed by the graphs of the equations 2x + 5y - 12 = 0, x + y = 3 and y = 0?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 3.
For 2x + 5y = 12.
| x | 1 | 6 |
| y | 2 | 0 |
For x + y = 3.
| x | 0 | 3 |
| y | 3 | 0 |
y = 0.
Area of bounded figure = 1/2 × 3 × 2 = 3 units2.
