Question

10. 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 1

Answer:

Hope it will help you!!

Step-by-step explanation:

Distance covered by Gaurav = 900m

Perimeter of the rectangular park = 900/15 = 60m

Let rhe breadth be x

So, the length = 2x

Breadth = 2(l + b) = 60

2(2x + x) = 60

4x + 2x = 60

6x = 60

x = 60/6

x = 10

Breadth = x = 10m

Length = 2x = 2 × 10 = 20m

Answer 2

Answer:

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}

perimetreofpark

=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
