Around the perimeter of the pool, which has a rectangular shape with sides of 50 meters and 25 meters

Around the perimeter of the pool, which has a rectangular shape with sides of 50 meters and 25 meters, they are pasted over with a special tape. How much time will the master spend if he glues 50 meters of tape in 1 hour?

1) Find the perimeter of the pool.

Since it has a rectangular shape, for this we sum up the lengths of all its sides.

We get:

50 + 25 + 50 + 25 = 150 meters.

You can also use the following expression:

2 * (25 + 50) = 2 * 75 = 150 meters.

2) Determine the time of the wizard.

We divide the perimeter of the pool by the productivity of the master.

Thus it will be:

150/50 = 3 hours.

Answer: The foreman will need 3 hours for all the work.
