योग

उत्तर


The given shape contains a semi-circle and a triangle.

Area of semicircle

= `1/2 πr^2`

= `1/2 xx 22/7 xx 10 xx 10`

= `1100/7`cm2

Area of triangle

= `1/2` × Base × Height

= `1/2 xx 20 xx 7`

= 70 cm2

Hence, total area enclosed by the shape

= `1100/7 + 70`

= `(1100 + 490)/7`

= `1590/7`

= 227 cm2 (approx)
