Question

How long will it take a boy to go around a regular pentagon of side 17 m at the speed of 5 metre per minute

Answer 1

Answer:

17 minutes

Step-by-step explanation:

Perimeter of pentagon = distance travelled

= 5*side

=5*17

=85m

Speed= 5m/min

Time =distance /speed

=85/5

=17 minutes

Answer 2

We know that a pentagon has five sides, and a regular pentagon has all sides with equal measure.

So, perimeter of the pentagon = 17 multiplied by 5 = 85m

Distance traveled by the boy = perimeter of pentagon = 85m

speed of the boy = 5m/minute

∴Time = distance / speed

            =$\frac{85}{5}$

            = 17 minutes

Ans :- The boy will take 17 minutes to go around a regular Pentagon.
