Question

the length of a rectangular Park 2m is less than the thrice its breadth if the perimeter of the park is 156 metre . find the length and the breadth of the park​

Answer 1

Let the breadth of the rectangular park be x m

Let the length be (3x-2)m

Perimeter of the rectangular park=156m

According to the problem,

2*{(3x-2)+x}=156

=>2*{3x+x-2}=156

=>2*{4x-2}=156

=>8x-4=156

=>8x=156+4

=>8x=160

=>x=160/8

=>x=20

Breadth =20m

Length=3x-2

=3*20-2

=60-2

=58m

Answer 2

Answer:

78m

Step-by-step explanation:

Length= 2m

Breadth= let's assume the breadth to be 'x'

            = 3x-2

Perimeter of a rectangle is 2(l+b)

                                     156m= 2(2+3x-2)

                                     156m= 2(3x) [ -2 and 2 get's cancelled]

                                     156m=6x

                                      x=156/6

                                      x=26m

Breadth= 3(26)

            = 78m

I hope you understood.
