Question

the length of a rectangular plot is 6 m less than thrice it's breath . Find the dimensions of plot if it's perimeter is 148 m.​

Answer 1

Answer:

Breadth=x= 20 metres  and

Length=3x−6=3×20−6=60−6=54 metres.

Step-by-step explanation:

Let the breadth of a rectangle = x m.

Thrice its breadth=3x m

Length of a rectangle= 3x-6 m

Perimeter of  a rectangle = 2(l+b)

=2(3x−6+x)

=2(4x−6)

=8x−12

But we are given perimeter=148 m

8x−12=148

8x=148+12

8x=160

x=20 metres

Breadth=x= 20 metres

and Length=3x−6=3×20−6=60−6=54 metres.
