Answer:
The expression for length of fence in meters is: 6w+20 meters
Explanation:
Let l be the length and w be the width of the given garden
Then according to given statements
Eqn 1
As we have to find the length of fence to fully surround garden that means the perimeter has to be found.
The formula for perimeter is given by:
![P = 2(length+width)](https://img.qammunity.org/2022/formulas/mathematics/college/g0lqho57fuulcesu3i8fhkkdhewvu0hvgm.png)
Putting the values
![P = 2(2w+10+w)\\P = 2(3w+10)\\P = 6w+20](https://img.qammunity.org/2022/formulas/mathematics/college/swsffak8fk0o7ab0rxlphpp2w6h8pjad0j.png)
Hence,
The expression for length of fence in meters is: 6w+20 meters
