Answer:
The value of y is 16 miles.
Explanation:
It is given that the formula of parallelogram is, Area = base×height. We had given the height and the area so in order to find the base, we have to substitue the following values into the formula :
Let base be y miles,
Let area be 160 miles²,
Let h be 10 miles,
![area = base * height](https://img.qammunity.org/2021/formulas/mathematics/middle-school/pdh3k2hik8t2va6g3cjnemnxr5xzhq2wgo.png)
![160 = y * 10](https://img.qammunity.org/2021/formulas/mathematics/middle-school/zfq9vzcxefnsesw93zrpefscwd5yuv972x.png)
