Answer:
110 ft
Explanation:
Since the cattle pen should be rectangular with an area of 753 square feet, if one side is 26 ft long, the other side must be:
![L=(754)/(26)=29\ ft](https://img.qammunity.org/2021/formulas/mathematics/college/ilu1sd2j93v0d2xutydnitb78cjuebf900.png)
The total amount of fence needed is equal to the perimeter of the rectangular cattle pen. The rancher will need:
![P = 2*26+2*29\\P=110\ ft](https://img.qammunity.org/2021/formulas/mathematics/college/qv0ezx32ptioho0julp65k5i2k7otudxlp.png)
The total amount of fence needed is 110 ft.
