Question

The length of a rectangular park is thrice its breadth.If the perimeter of the park is 168 metre,find its dimensions.

Answer 1

Heya!
--------

◾Let the length of the Rectangular park be ' x ' m

◾Then it's length becomes 3 times i,e 3• x = 3x m .

◾Perimeter of Park => 168 m


Now, We know that Perimeter of Rectangle = 2× ( L + B )

=> 2× ( x + 3x ) = 168

=> ( x + 3x ) = 168/2

=> ( x + 3x ) = 84

=> 4x = 84

=> x = 84/4

✔x = 21


⭐Length of Rectangular plot is 63 m

⭐Breadth of Rectangular plot is 21 m

Answer 2

Heya !!

Let breadth of rectangular park be X units.

Length of rectangular park = 3 × ( Breadth of rectangular park ) = 3X units.

Perimeter of rectangular park = 168

2 ( Length + Breadth ) = 168

2 ( 3X + X ) = 168

2 × 4X = 168

4X = 168/2

4X = 84

X = 84/4

X = 21 units.

Breadth of rectangular park = X = 21 units.

And,

Length of rectangular park = 3X = 63 unit's.
