DA = _____ cm
Now, the sum of the lengths of the four sides
= AB + BC + CD + DA
= _____ cm + _____ cm + _____ cm + _____ cm = _____ cm
What is the perimeter?
Solution:

Question 2.
Measure and write the lengths of the four sides of a page of your notebook. The sum of the lengths of the foursides
= AB + BC + CD + DA
= _____ cm + _____ cm + _____ cm + _____ cm
= _____ cm
What is the perimeter of the page ?

Question 3.
Meera went to a park 150 m long and 80 m wide. She took one complete round on its boundary. What is the distance covered by her ?
Solution:
Length of the park = 150 m
Breadth of the park = 80 m
Perimeter of the park = 2 (length + breadth)
= 2(150 + 80)
= 2 × 230 = 460 m
So, distance covered by Meena = 460 m.
