Question

Find the perimeter of the following shape​

Answer 1

$\huge\mathcal{\fcolorbox{red}{gray}{\green{A}\pink{N}\orange{S}\purple{W}\red{E}\blue{R}{!}}}$

Perimeter :-

Diameter of Semi circle = 2.8cm

Radius of Semi circle = $\dfrac{D}{2}$= $\dfrac{2.8}{2}$= 1.4cm

Perimeter of semi circle = πr + 2r

= $\dfrac{22}{7} × 1.4 + 2 × 1.4$

=> 4.4 + 2.8 cm

=> 7.2 cm

Sides of triangle = 3cm , 3cm , 2.8cm

Perimeter of triangle = Sum of all sides

= 3 + 3 + 2.8 cm

= 8.8cm

Perimeter of whole figure = perimeter of triangle + perimeter of semi circle

= 7.2 + 8.8 cm

= 16 cm

Answer 2

16 cm
