Answer:
We have the final answer as
36.4 km
Explanation:
Area of a parallelogram = base × height
Since we are finding the base ,
![base = (area)/(height) \\](https://img.qammunity.org/2021/formulas/mathematics/high-school/cq5qkkw0450v6gihuv69fgqf3er7q4szb8.png)
From the question
area = 1274 km²
height = 35 km
The base of the parallelogram is
![base = (1274)/(35) = (182)/(5) \\](https://img.qammunity.org/2021/formulas/mathematics/high-school/ih7hr6smcqagmctl73649v1nqswttalnp7.png)
We have the final answer as
36.4 km
