PLEASE MARK THE ANSWER AS BRAINLIEST...LIKE IT...I HAVE SOLVED ASSUMING YOU KNOW THE FORMULA IF NOT WRITE IN MY INBOX

Step-by-step explanation:

Area of square = $7^{2}$ = 49 cms

Area of circle = 3.14 * 3.5 * 3.5 =  38.465 cms

If the circle is removed from the sqaure then the remaining area will be

= Area of square - Area of circle

= (49 - 38.465) cms

= 10.535  cms
