Solution

The correct option is A

310


Let the equations of the sides BC, CA and AB of the triangle ABC be represented by
2y - x = 5 ...(1)
y + 2x = 7...(2)
y - x = 1 ......(3)
Solving the above 3 equations (1),(2)and(3),we get A(2, 3), B(3, 4) and C(95,175)=12{2×43×3+3×1754×95+95×3175×2}=12(89+515365+275345)=310units.
