Question

The length of a rectangular park is 3 times that of its breadth if the length of the diagonal is 16root10 metre then what is its perimeter

Answer 1

Step-by-step explanation:

Let the breadth be x meters.

Then,

The length is thee times it's breadth =3x m

perimeter of a rectangle

= 2 (l+b)

=2 (3x+x)

=2 (4x)

=8x

Perimeter of the park =192 meters

=192=8x

=8x=192

=x=192/8

=x=24

Hence , Breadth =x =24 m

Length =3x

=3×24

=72.
