Question

PARKS Anika is hiking on a rectangular trail at the national park. There are four resting spots along the corners of the trail. On the map, they are marked with coordinates of (-2, 2), (1, 2), (1, -2), and (-2, -2). If each unit represents 1 mile, find the perimeter of the trail in miles, using the coordinates.

Answer 1

15 units sq

Explanation:

Good job

Answer 2

`14\ miles`

Explanation:

Let

`A(-2, 2), B(1, 2), C(1, -2),D(-2, -2)`

Plot the coordinates

see the attached figure

we know that

The perimeter is equal to

`P=2(AB+AD)`

we have

`AB=(1-(-2))=3\ units`

`AD=(2-(-2))=4\ units`

substitute

`P=2(3+4)=14\ units`

Convert to miles

If each unit represents 1 mile

then

`14\ units=14\ miles`
