# Find the area of the region {(x,y): x2 + y2 ≤ 4, x + y ≥ 2}  [CBSE 2012]

The equation of the given curves are

X2 + y2 = 4 (i)

X + y = 2 (ii)

Clearly X2 + y2 = 4 represents a circle X + y = 2 is the equation of a straight line cutting x and y axes at (0, 2) and (2, 0) respectively.

These are shown in the graph below: The required area is given by We have y1 = 2 – x and y2 =        the area of the region {(x,y): x2 + y2 4, x + y 2}is Rate this question :
