Question

The sides of a triangular field are 25 m 20 m and 16 m find the total distance covered by a girl in taking two runs of this field

Answer 1

Answer:

If the sides of a triangular field are 25 m 20 m and 16 m, then the total distance covered by a girl in taking two runs of this field is 122m.

Step-by-step explanation:

If side of triangle are a = 25 m, b = 20m and c = 16 m

Here we have to find out the total distance covered by a girl in taking two runs of this field. So, first, find out the distance in one run. This means finding out the perimeter of the triangle.

Perimeter of triangle = Addition of all three sides

= a + b + c

= 25 + 20 + 16

= 61 m

So,   the distance in one run = 61m

Hence, the total distance covered by a girl in taking two runs of this field = 2 (61) = 122 m.
