Question

If a ladder of length 15.2 meter lean on a wall of 14 meter. Which equation gives the distance 1

between the foot of the ladder and the wall? *​

Answer 1

Distance between foot of ladder and wall = 5.92 meter (Approx.)

Explanation:

Given:

Length of ladder = 15.2 meter

Length of wall = 14 meter

Find:

Distance between foot of ladder and wall

Computation:

Length of ladder = Hypotenuse

Length of wall = Perpendicular

Distance between foot of ladder and wall = Base

Using Pythagoras theorem;

Base = √Hypotenuse² - Perpendicular²

Distance between foot of ladder and wall = √Length of ladder² - Length of wall²

Distance between foot of ladder and wall = √15.2² - 14²

Distance between foot of ladder and wall = √231.04 - 196

Distance between foot of ladder and wall = √35.04

Distance between foot of ladder and wall = 5.9194

Distance between foot of ladder and wall = 5.92 meter (Approx.)
