Question

The length of a rectangular park is thrice its breath. If the perimeter of the park is 168 meters, find its dimensions ​

Answer 1

Answer:

Step-by-step explanation:

Let the breadth of this rectangle be x

and the length of this rectangle be 3x

A/Q

2(Length + Breadth) =perimeter of rectangular park.

2( 3x + x ) = 168 metres.

6x + 2x = 168 metres.

8x = 168 metres.

x = (168/8) metres.

x = 21 metres.

then, breadth = x = 21 metres.

and length = 3x = 3× 21 = 63 metres.

Answer 2

Answer:

Step-by-step explanation:

Let the breadth be y.

Length = 3y

According to problem,

2(y + 3y) = 168

4y = 84

y = 21

Therefore,

Breadth = 21 m

Length = 3 x 21 = 63 m
