Question

Meera went to a rectangular park $140m$ long and $90m$ wide. She took $5$ complete rounds on its boundary. What is the distance covered by her?

Answer 1

Finding the perimeter of the rectangular park

Length of the park $=140m$

Width of the park $=90m$

Perimeter of the rectangle $=2\times \left(l+b\right)$

Perimeter of the rectangle $=2\times \left(140+90\right)$

$=2\times \left(230\right)=460m$

Finding the distance covered by Meera

Distance covered by Meera $=5\times perimeter$

Distance covered by Meera $=5\times 460=2300m$

Hence, the distance covered by Meera is $2300m$.
