Question

the perimeter of a rectqngular pattern is 640m If the length of the garden is thrice its breadth find the demension of the garden

Answer 1

p=640m

p=2(l+b)

let breadth be x

l=3x

therefore,

2(l+b)=640

2(x+3x)=640

2*4x=640

8x=640

x=80

breadth=x=80m

length=3x=3*80=24m

Answer 2

Answer:

640=2(l+b)

320=l+b

320=3b+b....[l=3b]

320=4b

80=b

l=3b=3×80=240

So, Length=240m

Breadth=80m

Hope this helps!
