Answer 2

Given PQRS is the diameter of circle of radius 10.5cm

So...

PS=10.5×2=21cm

Given PQ=QR=RS

So PQ=7cm, QR=7cm, RS=7cm

➡️So perimeter of the shaded portion of area= [π×(21/2)]+[π×(7/2)]+[π×(14/2)]

=33+77+22= 132cm

➡️ Area of the non-shaded portion=

[(π/2)×(21/2)²]+[(π/2)×(14/2)²]- [(π/2)×(7/2)²]

=231cm²

Hope it helped u
