than the route around its edges?

Answer 1

The length of the shortest route(the diagonal of the rectangle ) =

By using Pythagoeus Theorem,(We use it because a diagonal diivides a rectangle into two right angled triangles.)

${a}^{2} + {b}^{2} = {c}^{2}$

${60}^{2} + {80}^{2} + = {c}^{2}$

$3600 + 6400 = 10000$

${c}^{2} = \sqrt{10000}$

${c} = 100$

The shortest route is of 100 metres.

If the person goes around the edges,the distance will be (80+40) = 140 metres.

The difference of routes =140 -100

=40 metres

The diagonal route is 40 metres ahorter than the route along the edges.
