Q2.

Measure and write the lengths of the four sides of a page of your notebook. The sum of the lengths of the four sides = AB + BC + CD + DA = ___ cm +___ cm +___ cm +___ cm = _____ cm

Answers (1)

My note is rectangular in shape and each side are

AB=15cm 

BC=10 cm

CD =15cm

DA=10cm

AB+BC+CD+DA=15+10+15+10=50cm

Suppose the length of a rectangle=l cm and breadth=b cm, then 

The perimeter of the rectangle=2(l+b)

In the above rectangle let AB be the length and BC be the breadth, then

Perimeter = 2(AB+BC)=2(15+10)=2(25)=50cm
