Find the area of the triangle whose vertices are

((a+1) (a+2), (a+2)), ((a+2) (a+3), (a+3)) and ((a, 3) (a+4), (a+4))

Given, A triangle whose vertices are A ((a+1)(a+2), (a+2))


B ((a+2)(a+3), (a+3)) and C = ((a+b)(a+4), (a+4)).


To find: Find the area of a triangle.



Since, Area of triangle =


Then, =


=


=


Common terms will be canceled out


=


Hence, = 1 sq unit
