I)area of shape =area of semicircle +area of rectangle
=1/2πr2+b×h
=1/2×22/7×2×2+4×3
=22/7×2+12
=44/7+12
=6.28+12
=18.28 cm sq
II)area of shape=area of rectangle +area of semicircle+area of another semicircle
=4×3+1/2×22/7×2×2+1/2×22/7×1×1
=12+44/7+11/7
=12+6.28+1.57
=18.28+1.57
=19.85 cm sq
=1/2πr2+b×h
=1/2×22/7×2×2+4×3
=22/7×2+12
=44/7+12
=6.28+12
=18.28 cm sq
