Step-by-step explanation:
Circle: r = 3.5cm
Square: a = 28cm
Area of square = 28²
=784cm²
Area of circle = πr²
=22\7*3.5*3.5
=38.5cm²
Total no of circles that could be cutted = 784\38.5
= 20 circles could be cutted from the sheet
Remaining area of the sheet = Area of sheet - area of 20 circles
=784 - 20(38.5)
=784-770
= 14cm²
