in the mare drawn on the paper,find the distance covered by the tyre of a car of radius 28cm of thousand revolution ​

Answer 1

Answer:

Given

Perimeter =108cm

Breadth =20cm

Let length be l

2(l+b)=108cm

2(l+20)=108cm

2l+40=108cm

l=108-40/2

l=34cm

Step-by-step explanation:

Answer 2

Answer:

Width = 20 cm

Perimeter = 108 cm

=> 2 (Length +Width) = 108

=> Length +Width = 54

=> Length + 20 = 54

=> Length = 54 - 20

=> Length = 34 cm
