Question

Mitali runs around a square field of side 70 metres and Noori runs around a rectangular field of length 80 metres and breadth 50 metres.If both of them go around twice then the different between the distance covered by Mitali and Noori is

Answer 1

mitali runs =70×4=280m in one time
and
noori runs=2 (80+50)
=2(130)
260m in one time
therefore 280×2-260×2
560-520
=40
therefore difference between the twice distance covered by mitali and noori is 40m

Mitali:

He ran twice around the perimeter of a square,

$= 2 * 4s$

$= 2 * 4(70)$

$= 2 * 280$

$= 560$

Noori:

She ran around a rectangular field twice,

$=2 * 2(l+b)$

$= 2* 2(50+80)$

$= 2 * 2(130)$

$= 2* 260$

$= 520$

Time to find the difference!

$=\ \textgreater \ 560 - 520$

$=\ \textgreater \ 40$
