Question

semi circular lawns are attached to all edges measuring 21×14 find area of total field

Answer 1

Ar.of rec. Field = 21×14 = 294 sq.units

Ar.of two semicircles having diameter 21 cm = 2×1/2×22/7×21/2×21/2 = 346.5sq.units

Ar. of two semicircles having diameter 14 cm = 2×1/2×22/7×14/2×14/2 = 154sq.units

Hence,Total area of field= 294+346.5+154 = 794.5 sq.units
