please someone answer this question​

Answer 1

Answer:

536cm2

Step-by-step explanation:

Radius of circular sheet(R)=14cm and Radius of smaller circle(r)=3.5cm

Length of rectangle(l)=3cm and breadth of rectangle(b)=1cm

According to question,

Area of remaining sheet=Area of circular sheet−[Area of two smaller circle+Area of rectangle]

=πR

−[2(πr

×3.5×3.5)−(3×1)]

=22×14×2−[44×0.5×3.5+3]

=616−80

=536cm 2

Therefore the area of remaining sheet is 536cm 2
