Juan cuts a piece of rope that is 16 meter long into 2 equal pieces. What is the length of each shorter piece of rope? Enter you
denis-greek [22]

Answer:

\text{Length of each shorter piece of rope}=8\text{ meter}

Step-by-step explanation:

We have been given that Juan cuts a piece of rope that is 16 meter long into 2 equal pieces. We are asked to find the length of each shorter piece of rope.

To find length of each shorter piece of rope, we will divide total length of rope by 2 because Juan cuts the rope into two equal pieces.

\text{Length of each shorter piece of rope}=\frac{16\text{ meter}}{2}

\text{Length of each shorter piece of rope}=8\text{ meter}

Therefore, the length of each shorter piece of rope would be 8 inches.

the area of asquare field is 2.25 hectares.find its perimeter in metres if hectare is qual to 10000square metres​
Sergio [31]

Answer:

Perimeter of the square field is 600 meters.

Step-by-step explanation:

Given:

Area of a square field = 2.25 hectares

1 hectare = 10000 m²

∴2.25 hectares =2.25\times10000 = 22500 m²

Now, let each side length of the square field be a meters.

∴ Area = a^{2}

⇒ 22500 = a^{2}

⇒ a=\sqrt{22500}=150 m

Now, perimeter of a square is given as, P = 4a.

Here, a=150 m.

∴ P=4\times150=600 m

Hence, the perimeter of the square field is 600 meters.
