Answer:

(d) area of the circle – area of the triangle + area of the square

Explanation:

The circle and square are shaded, so their areas appear in the area formula with a positive sign.

The triangle is not shaded, so its area appears with a negative sign.

The matching choice is the last one (d):

area of the circle – area of the triangle + area of the square
