Question

Find the perimeter of a rectangle whose length and breadth are 40cm 0.3m​

Answer 1

Step-by-step explanation:

100cm=1m

40cm=40/100

=0.4m

perimeter of rectangle=2(l+b)

=2(0.4+0.3)

=2x0.7

=1.4

Answer 2

Answer:

Given:

Length= 40cm

Breadth = 0.3m

We must change 40cm into m

So 100cm = 1m

40cm = 40/100

=0.4 m

Perimeter of rectangle = 2(l+b)

Putting values in above formulae

Perimeter of rectangle = 2(0.4+0.3)

= 2(0.7)

= 1.4m
