Answer:
24.9 m
Explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as the equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.
You walk 21.5 m straight east and then 12.5 m straight north. This forms a right angled triangle with a horizontal distance of 21.5 m, a vertical distance of 12.5 m and the hypotenuse is the distance between the ending and starting point. Let x represent the distance between the ending and starting point. Therefore using Pythagoras theorem:
x² = 21.5² + 12.5²
x² = 462.25 + 156.25
x² = 618.5
Taking square root of both sides:
√x² = √618.5
x = √618.5
x = 24.9 m = distance between the ending and starting point.
