Answer:

350 cm square

Step-by-step EXPLANATION:

DC + DC/2 = 21 (DC= AC and radius of semicircle = AC/2 = DC/2)

3DC/2 = 21

DC = 7×2 = 14

radius = DC/2 = 7

Area of figure = area of square + area of semicircle

= 14×14 + PI(7)^2 = 14(14 + 11) = 350 cm square

do CHECK the calculation once but this will be the method
