Perimeter And Area Questions For Class 6 – Problem-based on circumference of a circle

Question 16

The diameter of a wheel of a car is 42 cm. Find the distance covered by the car during the time in which the wheel makes 1600 revolutions?

Radius of the wheel = 42/2 cm = 21 cm

Circumference of the wheel = 2πr

= 1.32 m ( As we know that, 1 m = 100 cm )

Distance covered by wheel in 1 revolution = Circumference of the wheel

Distance covered by wheel in 1 revolution = 1.32 m

Distance covered by wheel in 1600 revolutions = ( 1.32 x 1600 ) m

= 2.112 km ( As we know that, 1 m = 1000 km )

Perimeter And Area Questions For Class 6 – Problem based on Perimeter of rectangle

Question 19

The length and the breadth of a rectangle are in the ratio 2 : 5 . If its perimeter is 28 m , find its dimensions.

Let, length and breadth be 2y m and 5y m

Since, perimeter of rectangle = 2 (l+b) units = 2 ( 2 y + 5 y ) m = ( 2 x 7 y ) m = 14ym

But, perimeter of rectangle = 28 m

Since, 14 y = 28 y = 28/14

So, length = ( 2 x 2 ) m = 4 m breadth = ( 5 x 2 ) m = 10 m
