Find out the perimeter of the following figure
Perimeter = 5cm + 5cm + 5cm
Perimeter = 15 cm
Perimeter = 4cm + 3cm + 5cm
Perimeter = 12 cm
Perimeter = 5cm + 5cm + 3cm + 3cm
Perimeter = 16 cm
Perimeter = 2cm + 3cm + 4cm + 4cm + 1cm + 4cm + 1cm
Perimeter = 19 cm
Perimeter = 20 cm + 25 cm + 20 cm + 50 cm
Perimeter = 115 cm
Perimeter = 2cm + 6cm + 4cm + 4cm + 3cm
Perimeter = 19 cm

5.) Rectangle has its length 50 cm and breadth 30cm . Calculate the perimeter of rectangle
Answer: Perimeter of rectangle = 2(length) + 2(breadth)
Perimeter of rectangle = 2 × 50 + 2 × 30
Perimeter of rectangle = 100 + 60
Perimeter of rectangle = 160 cm
6.) Perimeter of rectangle is 26 m. And sides of rectangle are 3m , 10 m and 3m. Calculate the measurement of fourth side
Answer: Let fourth side be X
Perimeter = 3m + 10 m + 3m + X
22 = 16 m + X
X = 26 -16
X = 10 m
7.) Calculate Perimeter of Triangle having sides 8 m , 8m and 10 m
Answer: Perimeter of triangle = 8m + 8m + 12m
Perimeter of triangle = 28m
8.) Find out Perimeter of triangle
Answer: Perimeter of triangle = a + b + c
9.) Find out Perimeter of Square
Answer: Perimeter of Square = 4 × a
Sides of Square are all equal
10.) Find the perimeter of the following
Answer:
a) Perimeter = 5m + 6m + 4m + 6m + 5m
Perimeter = 26m
b) Perimeter = 6m + 9m + 8m + 9m + 6m
Perimeter = 38m
c) Perimeter = 3cm + 4cm + 3cm + 2cm
Perimeter = 15cm
d) Perimeter = 3 ft + 9 ft + 3 ft + 6 ft
Perimeter = 21 ft.
