• Given image and formulas and asked to calculate the perimeter of the figure.

$\huge {\bf{\orange{\mathfrak{Answer:-}}}}$

• First, Understand the figure.

• $\boxed {Perimeter \: \: of \: \: the \: \: given \: \: figure = AB + BC + CD + DE + EF + FG + GH + HA }$

• We know that AB = CD + DG { Opposite sides of Rectangle }

• $\therefore {AB = 9.1 + 4.1 = 13.2 }$ {EF and DG are equal i.e opposite sides of square}

• Now, AB + BC + CD + DE + EF + FG + GH + HA =

• 13.2 + 6.1 + 9.1 + 4.1 + 4.1 + 4.1 + 8.3 + 8.3 =

• $\boxed { 57.3 \: yards. }$

$\huge{\bf{\red{\mathfrak{Conclusion:-}}}}$

• $\boxed{\therefore{ Perimeter \: \: of \: \: the \:\: given \:\: figure \: = \: 57.3 \: \: yards. }}$

$\huge{\bf{\blue{\mathfrak{Extra \: Information:-}}}}$

• Perimeter is the distance or boundary around a 2 dimensional figure.

• Perimeter of square = 4 * side = 4s

• Perimeter of Rectangle = 2 ( l + b )

• Perimeter of Triangle = a + b + c

Answer 2

Answer:

Solution :-

At first finding perimeter of AB

Perimeter = 2(7.1 + 6.3)

=> 2(13.4)

=> 26.8 y

Now,

Perimeter of AGH

=> 7.1 + 8.3 + 8.3

=> 7.1 + 16.4

=> 23.5 y

Now,

Perimeter of FE = 4 × 4.1

=> 16.4 y

Now,

Total perimeter = S1 + S2 + S3

=> 26.8 + 23.5 + 16.4 y

=> 66.7 cm
