Question : What is the area of the region bounded by a straight line $9x+4y=36$, x-axis and the y-axis?
Option 1: 12 sq. units
Option 2: 18 sq. units
Option 3: 16 sq. units
Option 4: 15 sq. units
Correct Answer: 18 sq. units
Solution : $9x+4y=36$ can be written as $\frac{9x+4y}{36}=1$ $⇒\frac{x}{4} + \frac{y}{9} = 1$ $\therefore$ Area = $\frac{1}{2}\times OA\times OB=\frac{1}{2}\times 4 \times 9$ = 18 sq. units Hence, the correct answer is 18 sq. units.
