Answer:
536cm²
Step-by-step explanation:
Radius of circular sheet (R)= 14 cm and radius of smaller circle (r) 3.5 cm Length of rectangle (1)-3 cm and breadth rectangle (b) 1 cm
Area of the remaining sheet-Area of circular sheet (Area of two smaller circle + Area of rectangle) =R-2rr²+(length x Breadth)
14-(#×3.5×3.5+3)
=22x2x14
-616-(22×3.5+3)
-616-(77+3)
-616-80
-536 cm²
Therefore, the area of remaining sheet is 536 cm².
