b)50 sq. units
c)75 sq. units
d)100 sq. units
e)depends on the value of a

C is the answer. y = |x+a| is a modulus graph. It will change the position, based on the value of 'a', but not the shape. It is a V-shaped graph, that will make a triangle with y = 5. The base and the height will be 10 and 5, respectively, hence the area will be 75.

Hello S. Nath,
Please find the solution
OA = 7, height = y
7 x y =21 => y =3
Co-ordinate of B (10, 3)

It's simply half of a square whose diagonal length is 10. So required area = 25.
