Question

Helen has a rectangular garden that measures 65 meters by 20 meters. how long is the diagonal length of the garden? (an example of diagonal length is from the top left corner to the bottom right corner of the garden.)

Answer 1

The diagonal of an object is the line that join the two vertices which are not on the same edge of the polyhedron or polygon. By joining these points in the rectangular garden above we would divide the garden into two right triangles. We can determine the length of the diagonal by Pythagorean theorem:

Diagonal = √(65^2 + 20^2)
Diagonal = 5√185 m = 68.01 m
