Question

the lenghy of the rectangular field is 3 times it's breadth if the area of the field is 192 cm then find its breadth


​

Answer 1

Answer:

Length of a rectangular field is 2 times its breadth.

Perimeter of the field = 72cm.

Let the breadth of the rectangular field be "x"cm.

Then its length will be 2x.

We know that,

The perimeter of a rectangle =

2(length + breadth)

According to the question,

=> 2(length+breadth) = 72cm.

Putting the value of expected values of length and breadth in their respective places.

2( 2x + x) = 72cm

4x + 2x = 72cm

6x = 72cm

x = 72/6

x = 12 cm

Therefore,

Length of the field = 2x = 2*12

= 24cm..

Breadth of the field = x

= 12cm..
