Question

The length of a rectangular field is 30m and its diagonal is 34m ..find its breadth

Answer 1

Answer:

It is given that,

Length of a rectangular field = 30 m.

Diagonal of a rectangular field = 34 m.

Consider the breadth of rectangular field = b m.

Using the Pythagoras theorem,

AC

=AB

+BC

Substituting the values,

34

2

=30

2

+b

By further calculation,

1156=900+b

2

So we get

b

=1156–900=256

b=

256

=16 m

We know that,

Perimeter = 2(l+b)

Substituting the values,

=2(30+16)

=2∗46

=92 m.
