Question

perimeter of the hall.
The length of a rectangular playground is thrice its breadth. If the perimeter of the playground is
56 metres, find its dimensions​

Answer 1

Answer:

Let the breadth be x

And the length be 3x

ATQ,

2(x+3x) = 56

2x + 6x = 56

8x = 56

X = 7

Length = 3x = 21m

Breadth = x = 7m

Please mark it as brainliest :-)

Answer 2

Answer:

length=7

breadth=21

Step-by-step explanation:

let,

b=x

l=3x

2(l+b)=56

2(3x+x)=56

8x=56

x=7

3x=21
