Question

What is the area of the shaded region?____ square miles.

Answer 1

Finding the area of the shaded part means finding the area of the yellow triangle,

The exercise provide us the base and the height of the triangle, so we must replace these values in the next equation

`A_(triangle)=(b\cdot h)/(2)`

Where, b is the base and h is the height

`A=\frac{5\text{ mi}\cdot4\text{ mi}}{2}=\frac{20\text{ mi}}{2}=10\text{ mi}`

So, the area of the shaded region is 10 mi.
