Answer:
Step-by-step explanation:
→ Area of the paper=l*b [since its a rectangle]
=30*21
=630 square cm
→ Now the radius of the largest circle will be 10.5 cm
→ Hence the area of the circle so formed will be 346.36
→ And the area of the left portion will be =630-346.36
=283.64

Step-by-step explanation:
AREA OF RECTANGLE = l*b
AREA OF CIRCLE = πr²
BIGGEST AREA OF THE CIRCLE CUT OUT WOULD BE -
AREA OF RECTANGLE - AREA OF CIRCLE
=(30 * 21)-(22/7*10.5*10.5)
=630 - 346.185
=283.815 cm²
