1.	A line y=x+2 is drawn on the co-ordinate plane. This line is rotated by 90∘ clockwise about the point (0,2). Another line y=−2x+10 is drawn such that a triangle is formed by these three lines. If the area of the triangle is A sq. unit, then the value of 3A is
Answer» A line $y = x + 2$ is drawn on the co-ordinate plane. This line is rotated by $90^{\circ}$ clockwise about the point $(0, 2) .$ Another line $y = - 2 x + 10$ is drawn such that a triangle is formed by these three lines. If the area of the triangle is $A$ sq. unit, then the value of $3 A$ is
