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 she take to run once round the garden?

Answer 1

SOLUTION:-

PERIMETER OF TRIANGLE=25+20+16=61 m

DISTANCE TRAVELLED IN 2 ROUNDS= 61 x 2= 122 m

Answer 2

Answer:

160 steps

Step-by-step explanation:

Given : Rekha runs along the sides of a triangular garden whose sides are 35 m, 25 m and 20 m.

To Find :If she covers 50 cm in one step, how many steps will she take to run once round the garden?

Solution :

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

Perimeter of garden = Sum of all sides

                                 = 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 = $\frac{8000}{50}step$

                    = $160 step$

Hence she will take 160 steps to run once round the garden.
