Step-by-step explanation:
we can clearly see that this images formed by a rectangle and two semicircles.
perimeter = 14+21+circumference of the two semicircles
=14+21+π(14/2+21/2)
=35+22/7(35/2)
=35+22/7×35/2
=35+11+5
=51units
now area =area of rectangle + area of the two semi circles.
=14×21+π/2(14/2)²+π/2(21/2)²
=294+22/14×14/2×14/2+22/14×21/2×21/2
=294+22/2×14/2+22/2×3/2×21/2
=294+11×7+1386/8
=294+77+173.25
=(544.25)sq.unit
