1.

The area of the region bounded by the curuse `y=|x-2|,x=1,x=3` and the x-axis isA. 4B. 2C. 3D. 1

Answer» Correct Answer - d
Let A be the required area. Then, `A=underset(1)overset(3)(int)|x-2|dx`
`impliesA=underset(1)overset(2)(int)-(x-2)dx+underset(2)overset(3)(int)(x-2)dx`
`impliesA=[2x-(x^(2))/(2)]_(1)^(2)+[(x^(2))/(2)-2x]_(2)^(3)=1/2+1/2=1`
