Solution

In rectangle ABCD, BC = 14 cm

∴ Radius of each circle = `14/2 = 7` cm

∴ Length of rectangle = `(7 + 7 + 7) xx 2`

= 42 cm

Now area of rectangle = `l xx b = 42 xx 14`

= 588 cm2

and area of 3 circles = `3 xx pir^2`

= `3 xx 22/7 xx 7xx 7 = 462` cm2

∴ Area of shaded portion

= 588 - 462 = 126 cm2

Concept: Area of Circle
