Answer:
56cmsquared
Step-by-step explanation:
if you look clearly at that question that diagram which has the coloured part out of that small square comes a quarter circle.
now take that quarter circle and get its area .
then put a dotted line such that they'll be formation of a triangle in that quarter circle.
then get the area of that quarter triangle in minus it from the area of the quarter circle.
and you'll get the area of 1 shaded part because you had subdivided those shaded parts by the dotted line you had kept earlier in order to emerge with a triangles
after that what multiply what you got by two to get the whole shaded part then finalize by multiplying by two because two shapes were shaded.
good day
