Question

Area of triangle formed by straight lines $3x-4y=0,x=4$ and $x-$ axis is:

• A. $6$ sq. unit
• B. $8$ sq. unit
• C. $12$ sq. unit
• D. $16$ sq. unit

Answer 1

The correct option is A $6$ sq. unit

$3x-4y=0$

$4y=3xy=\frac{3}{4}x-\left(1\right)$

$puttingx=4ineq\left(1\right)$

$y=\frac{3x}{4}$

$y=\frac{3}{4}\times 4$

$y=3$

$Area=\frac{1}{2}\times base\times height$

$Area=\frac{1}{2}\times 4\times 3$

$Area=6squnits$
