Given:
Kelly left her house for a shopping mall. She started walking to the west 12 m. She took a left and walked a for 1 m, took a left again and walked for 2 m.
To find:
How far is she the mall from her house?
Solution:
From the given information, we have the data as follows.
Kelly left her house for a shopping mall. She started walking to the west 12 m. She took a left and walked a for 1 m, took a left again and walked for 2 m.
Consider the attached figure while going through the following steps.
From the figure it's clear that, we are supposed to find the distance that is equal to a side of a triangle having other sides equal to 1 m and the 10 m.
The distance is,
x² = 1² + 10²
x² = 1 + 100
x² = 101
x = √101
x = 10.04 m.
Therefore, Kelly is 10.04 m away from the house.
