Answer 1

Answer:

160 steps

Step-by-step explanation:

Sides of triangular garden  = 35 m , 25 m , 20 m

Perimeter of garden = Sum of all    = 35+25+20  = 80 m

1 m = 100 cm

So, 80 m = 8000 cm

50 cm = 1 step

1 cm = $\frac{1}{50} step$

So, 8000 cm =  $\frac{8000}{50} steps$

                   = 160 steps

                               

Answer 2

Answer:

Question :

↝ Rekha runs along the sides of a triangular Garden whose sides are 35 m, 25 m and 20 m. If she covers 50 cm in one step, how many steps will take to run once round in the garden?

$\begin{gathered}\end{gathered}$

Given :

• ➠ Side of triangular garden = 35 m, 25 m and 20 m.
• ➠ Rekha cover 50 cm in one step.

$\begin{gathered}\end{gathered}$

To Find :

• ➠ How many steps will take to run once round in the garden?

$\begin{gathered}\end{gathered}$

Using Formulas :

${\longrightarrow{\small{\underline{\boxed{\sf{Perimeter \: of \: triangle = Sum \: of \: all \: sides}}}}}}$

${\longrightarrow{\small{\underline{\boxed{\sf{1 \: m = 100 \: cm}}}}}}$

$\begin{gathered}\end{gathered}$

Solution :

☼ Finding the perimeter of triangular garden :-

${\dashrightarrow{\sf{Perimeter_{(Triangle)} = Sum \: of \: all \: sides}}}$

${\dashrightarrow{\sf{Perimeter_{(Triangle)} = 35 \: m + 25 \: m + 20 \: m}}}$

${\dashrightarrow{\sf{Perimeter_{(Triangle)} = 80\: m}}}$

${\bigstar \: {\underline{\boxed{\sf{\red{Perimeter \: of \: triangle = 80\: m}}}}}}$

∴ The perimeter of triangular garden is 80 m.

☼ Now converting the 80 m into cm :-

${\dashrightarrow{\sf{1 \: m = 100 \: cm}}}$

${\dashrightarrow{\sf{80 \: m = 80 \times 100}}}$

${\dashrightarrow{\sf{80 \: m = 8000 \: cm}}}$

${\bigstar \: {\underline{\boxed{\sf{\red{80 \: m = 8000 \: cm}}}}}}$

∴ 80 m = 8000 cm.

━┅━┅━┅━┅━┅━┅━┅━┅━┅━

☼ Now, finding the number of steps will take to run once round in the garden :-

${\dashrightarrow{\sf{50 \: cm = 1 \: step}}}$

${\dashrightarrow{\sf{1\: cm = \dfrac{1}{50}\: step}}}$

${\dashrightarrow{\sf{8000\: cm = \dfrac{1}{50} \times 8000}}}$

${\dashrightarrow{\sf{8000\: cm = \dfrac{8000}{50}}}}$

${\dashrightarrow{\sf{8000\: cm = \cancel{\dfrac{8000}{50}}}}}$

${\dashrightarrow{\sf{8000\: cm = 160 \: step}}}$

${\bigstar \: {\underline{\boxed{\sf{\red{8000\: cm = 160 \: step}}}}}}$

∴ The 160 steps will take to run once round in the garden.
