Question

Gourav takes 15 rounds of a rectangle park whose length is twice its

breadth. If the total distance covered by Gourav is 900m, find the length

and breadth of the park.​

Answer 1

Step-by-step explanation:

question:Gaurav takes 15 rounds of a rectangular park whose length is twice its breadth. If the total distance covered

by Gaurav is 900 m, find the length and breadth of the park.

answer:

length of park = 2 × breadth of park

= l = 2b=l=2b

$\begin{gathered}perimetre \: of \: park \: \\ = 2(l + b) \\ = 2(2b + b) \\ = 2 \times 3b \\ = 6b\end{gathered}$

perimeter of park =2(l+b)

=2(2b+b)

=2×3b

=6b

Gaurav takes 15 rounds of rectangular park by 900m

$\begin{gathered} = 15 \times 6b = 900m \\ = > 6b = \frac{900m}{15} \\ = > 6b = 60m \\ = > b = \frac{60m}{6} \\ = > b = 10m\end{gathered}$

=15×6b=900m =>6b= 15

900m

=>6b=60m =>b= 6

60m

=>b=10m

therefore, breath of rectangle =10m

given,l=2b

then,l=2×10m

=> l=20m

Answer 2

Answer:

he takes 15rounds of the park

and he covered total distance 900m

so, 1round is = 900/15

= 1 round = 60m

and rectangular park sides are x, 2x

x*2x=60

x*x=60/2

x2=30

x=

$\sqrt{30}$
