Perimeter of rectangle ABCD
= Sum of its 4 sides
A B
C
D
=AB + BC + CD + DA
Opposite side of rectangle are
equal
AB = CD (Length)
BC = DA (Breadth)
= AB + AB + BC +BC
= (2 X AB) + (2 X BC)
= (2 X Length) + (2 x Breadth)
= 2 x (Length+ Breadth)

5. How much lace would be required to
border it?

cm
6 cm
6 cm
Perimeter of rectangle
= 2 x (Length+ Breadth)
= 2 x (10cm + 6cm)
= 2 x 16 cm
= 32 cm

6. • Calculate the perimeter of this wooden frame. Its length is 15 cm and breadth are 20 cm.
Perimeter of wooden frame
= 2 x (Length+ Breadth)
= 2 x (15 cm + 20 cm)
= 2 x 35 cm
= 70 cm

7. Perimeter of a rectangle = 34 cm
Length of its one side = 4cm
What is the length of the other side ?
Step I
Divide perimeter by 2
So, 34/2
= 17 cm
Step II
Subtract one side from the result
= 17 cm – 4 cm
= 13 cm

8. The perimeter of a rectangular field is 60 cm.
Find the breadth of the field if its length is 18 cm.
Perimeter = 60 cm
Length = 18 cm,
Breadth = ?
Perimeter of rectangle = 2 x (Length+ Breadth)
60 cm = 2 x (18 cm + Breadth)
30 = 18 + B
B = 12 cm

All side of square are equal
AB = CD = BC = DA
Perimeter of square ABCD = Sum of its 4 sides
=AB + BC + CD + DA
= AB + AB + AB + AB
= 4 x AB
= 4 x (Side)

11. SIDE = 7 cm
Perimeter of square
= side + side + side + side
= 4 x side
= 4 x s
= 4 x 7 = 28 cm
Perimeter of square

12. • Find the perimeter of this table top. Its side is
30 cm.
Perimeter of table top
= side + side + side + side
= 4 x side
= 4 x s
= 4 x 30 = 120 cm

13. The perimeter of a square carpet is 200 m.
What is the length of on side?
Perimeter of square = 4 x side
200 = 4 x Side
Side =

15.  Jimmy us cycling around the rectangular garden whose length
and breadth is 120 m and 180 m respectively. He will take one
complete round of the garden. How much distance he will cover
after completion of one round?
Perimeter of rectangular garden = 2 x (Length+ Breadth)
= 2 x (120 m + 180 m)
= 2 x 300 m
= 600 m
