Question

Find the Perimeter of this figure​

Answer 1

Step-by-step explanation:

Perimeter of the figure =

As we know that the shaded triangle is a right angled triangle

By Pythagoras Theorem

Hypotenuse^2 = Perpendicular^2 + Base^2

Hypotenuse = 1^2 + 1^2

Hypotenuse = = 2cm

perimeter of the figure = ( 4 + 5 + 3 + 2 + 4 )cm

= 18cm

Answer 2

Question:-

Find The Perimeter Of This Figure.

Answer:-

$perimeter \: of \: This \:Figure = 2(l + b) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2(4 + 5) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =8 + 10 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 18cm$

So, The Perimeter Of This Figure Is 18cm
