Find the area of the coloured regions

Radius of smaller semicircle

= 7 cm

Radius of bigger semicircle = 14 cm

Area of smaller semicircle

= 77 cm²

= 308 cm²

Area of the coloured regions = (Area of bigger semicircle-Area of

smaller semicircle) + Area of smaller semicircle

Area of the coloured regions = (308-77) + 77

= 308 cm²
