### Describe in Detail

Essay▾The distance between 2 points A and B measured along the slope is 252m. Find the horizontal distance between A and B when

a. The angle of slope

b. Slope is 1 in 4.5

c. Difference in elevation of A and B = 35.07m

## Explanation

a. Horizontal distance =

## Alternative Method

- Correction for the slope distance, =
- Horizontal distance, D =

b. Slope is given as 1 in 4.5, i.e..

Horizontal distance, D =

## Alternative Method

- Correction for the slope distance, =
- Horizontal distance, D =

c. The difference in elevation, *h* = 35.07m

Hence,

Horizontal distance, D =
