The grade of the path in the mountain is calculated by determining first the ratio between the rise over the run and multiplying the ratio by 100%.
For Path A:
grade = (rise / run) x 100%
grade = (1414/ 3535) x 100% = 40%
<em>Answer: 40%</em>
For Path B:
grade = (rise / run) x 100%
grade = (4.26 m/ 22 m) x 100% = 19.36%
Answer: 19.36%
Perimeter = 2 * 85 + 2 * 125 = 420
85 * 125 = 10,625 area
70 by 140 = 420 perimeter
70 * 140 = 9,800 area
