Question

find the circumference of these figure​

Answer 1

length=7cm

breadth=21cm

radius = 21/2cm

circumference of the figure = 2 X perimeter semicircle - perimeter of rectangle

$2 \times \frac{2\pi \: r}{2} - 2(l + b)$

$2 \times 2 \times \frac{22}{7 } \times \frac{21}{2} - 2(7 + 21)$

$66 - 28 \times 2$

$66 - 56$

$10cm.$
