Answer:
Step-by-step explanation:
Rectangle
Length = 30cm
Breadth= 20 cm
Circle
Diameter= 20cm
Radius = 10cm
Area of rectangle = length × breadth
= 20 × 30
= 600 cm square
Area of circle = 22/7×10×10=2200/7=314.29cmsquare
Area of remaining sheet = area( rectangle) - area( circle) = 600-314.29=285.71cm square
