Answer:

Area of the left over aluminium sheet

= 23.44 cm^2

Step-by-step explanation:

Side of a square piece of an aluminium sheet (a) = 6 cm  

Area of a square = a^2

Radius  of a circle (r) = 2cm  

Area of a Circle = pi r^2

/* According to the problem given

Area of the left over aluminium sheet

= Area of the square - Area of the circle  

= a^2 - \pi r^2= 6^{2} - 3.14 times 2^{2}= 36 - 3.14 times 4= 36 - 12.56= 23.44 cm^{2}

Therefore.,

Area of the leftover aluminium sheet = 23.44cm^2
