Question

A school playground is 185 m long and 85 m wide . How much wire will be needed to encircle it 4 times?​

Answer 1

Answer:

length = 185m

breadth = 85m

perimeter = 2×(185+85)

=540

if we want to encircle ground four times = 4 ×540

2160

Answer 2

       $\underline{\bold{Answer:}}$

       $2160m$

       $\underline{\bold{Step-by-step-explaination:}}$

       $\text{It is given that a school playground is }185m \text{ long and }85m \text{ wide}$

$\implies \text{Length of playground}(L)=185m$

$\implies \text{Breadth of playground}(B)=85m$

      $\text{The wire must encircle the playground 4 times}$

$\implies \text{Length of wire}= 4(\text{Perimeter of playground})$

       $\text{Perimeter of playground}= \text{Perimeter of rectangle}= 2(L+B)$

$\implies \text{Length of wire}= 4[2(185+85)]$

$\implies \text{Length of wire}= 8(270)$

$\implies \boxed{\text{Length of wire} = 2160m}$
