Question

If the area of a triangle is $5$ sq.units, then the area of the triangle when the origin is shifted to $(1,2)$ is

• A. $2$ sq.u
• B. $3$ sq.u
• C. $4$ sq.u
• D. $5$ sq.u

Answer 1

The correct option is D $5$ sq.u

Area of triangle is independent of position of origin as all the co-ordinates will be shifted then and sides remain same.

$\therefore$ Area of triangle when the origin is shifted to $(1,2)$ is equal to $5$ sq.u.
