HEY Buddy.....!! here is ur answer
Given that : Side of square = 21 cm
Side of a square = Diameter of a circle
As we know that : Area of a square = (side)²
and area of a circle = πr²
According to the question : Area of left part of card board = area of square –area of Circle
=> Area of left part = (21)²–22/7×(21/2)²
=> Area = 94.5 cm²
So, the area of left part of card board will be 94.5 cm²
I hope it will be helpful for you...!!
THANK YOU ✌️✌️
