Answer 1

$\qquad\qquad\huge\underline{\boxed{\sf Answer}}$

Perimeter of given figure is equal to :

Perimeter of square - side length + quarter Circumference of the circle

that is :

$\qquad \sf \dashrightarrow \:(10 \times 4) - (5 + 5) + \dfrac{2 \pi r}{4}$

$\qquad \sf \dashrightarrow \:40- 10 + \dfrac{3.14 \times 5}{2}$

$\qquad \sf \dashrightarrow \:30+ \dfrac{15.7}{2}$

$\qquad \sf \dashrightarrow \:30 + 7.85$

$\qquad \sf \dashrightarrow \:37.85 \: \: units$

So, the required perimeter is 37.85 units
