Question

Q10 Sonu ran around a rectangular garden of length 20 cm and breadth 15 cm .Monu ran around a square field of side 25 cm .Who covered more distance and by how much ?​

Answer 1

Answer:

Monu covered more distance as he ran 100 cm and sonu ran around 70 cm, So monu covered more distance by 30 cm.

Step-by-step explanation:

Sonu ran around a rectanglular garden, so the distance covered is the perimeter of the rectangle

P= 2L+2B

= 2(20)+2(15)

=70 cm

Monu ran around a piece of square, so the distance covered is the perimeter of the square

P= 4L

= 4(25)

= 100 cm

So we can see that monu covered more distance as he ran 100 cm and sonu ran around 70 cm, So monu covered more distance by 30 cm.

Answer 2

length of a rectangular garden = 20 cm

breadth of a rectangular garden = 15 cm

area of a rectangular garden = l × b = 20 × 15

= 300 cm of sonu. and

area of square field = 25 cm

area of a square field = 4 × side = 4 × 25

= 100 cm of monu and

covered more distance = 300 - 100 = 200
