Question

find the perimeter of given figure answer is 24cm but I want the solution​

Answer 1

Answer:

6+ 2+ 6 + 1.5 + 1.5 + 3.5 + 3.5 = 24

Answer 2

Given:

Each length of the side of the polygon.

• Arrow of  seven sides,
• AB = 6 cm
• BC = 1.5 cm
• CD = 3.5 cm
• DE = 3.5 cm
• EF = 1.5 cm
• FG = 6 cm
• AG = 2 cm

Now,

To find the perimeter of the polygon,

We know that,

The perimeter = sum of all the sides

• To get the perimeter of the arrow polygon,

We have to add all sides of it.

The perimeter = AB+BC+CD+DE+EF+FG+AG

The perimeter = 6+1.5+3.5+3.5+1.5+6+2

The perimeter = 24 cm

Another method,

We observe that,

AB = FG = 6 cm

BC = EF = 1.5 cm

CD = DE = 3.5 cm

And AG = 2 cm separately.

So,

The perimeter = 2*(AB) + 2*(BC) + 2*(CD) + AG

The perimeter = 2*(6) + 2*(1.5) + 2*(3.5) + 2

The perimeter = 12 + 3 + 7 + 2

The perimeter = 24 cm

Hence,

• The perimeter of the polygon is 24 cm
