Question

A rectangular field is 300 m by 400m. What distance is saved by walking diagonally across the field?

Answer 1

Step-by-step explanation:

Distance if travelled on side =400+300m

=700m

Distance by diagonal=

$\sqrt{(300) ^{2} + (400)^{2} }$

=500m

distance saved =700-500m

=200m

Answer 2

Answer:

MARK ME AS BRAINLIEST MATE

Step-by-step explanation:

Given ABCD is a rectangular field of Length = 40m, Breadth = 30m, ZB=90

O

In the right angled triangle ABC,

By Pythagoras Theorem,

AC

=30

2

+40

=900+1600

=2500

..AC=

2500

= 50m

Distance from A to C through B is

=30+40-70m

Distance saved =70-50-20m.
