Forgot how to solve this lol....

Answer:
hi
Step-by-step explanation:
the first we must find the are of square
area of the square is 100 cm² (10 cm × 10 cm)
and we must find area of circle then we divide this area to 4
area of circle
[tex]a = \pi {r}^{2} [/tex]
3,14 × 10²=314
314/4=78,5 it is the 1/4 part of circle
then 78,5 + 100= 178,5
i think so
hope it helps
have a nice day
