Question

11. A rectangular track is 80m long
and 55m wide. What is the total
distance covered by a man if he takes
4 rounds of the track?​

Answer 1

$\huge\boxed{\underline{\sf{\red{A}\green{n}\purple{s}\orange{w}\blue{e}\pink{r:-}}}}$

$\sf{Rounds~ to~ be~ taken~ so ~perimeter.}$

$\sf{Length-80~m}$

$\sf{Breadth-55~m}$

$\sf{Perimeter-2×(Length+Breadth)}$

$\sf{2×(80+55)}$

$\sf{=270~m}$

$\sf{Four~rounds~so~Perimeter×4}$

$\sf{270×4}$

$\sf\pink{{=1080~m}}$
