Answer:
The value of y is 16 miles.
Step-by-step 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,
[tex]area = base \times height[/tex]
[tex]160 = y \times 10[/tex]
[tex]160 = 10y[/tex]
[tex]10y \div 10 = 160 \div 10[/tex]
[tex]y = 16 \: miles[/tex]
