Question

please tell me this answer

Answer 1

Let,
Breadth of rectangle=x
Length of rectangle=3x
So,
3x*x=1728
3x²=1728
x²=1728/3
x=√(576)
x=24 m
So,
Breadth=x=24 m
Length=3x=3*24=72 m
So,
Perimeter=2(l+b)=2(72+24)=2*96=192 m

Hope this helps you!

Answer 2

Given L=3b

Area =1728
L×b. =1728
3b×b =1728
3b^2 =1728
b^2. = 576
b =24
L = 3×24
L=72

Perimeter = 2(72+24)
=2(96)
=192

HOPE IT HELPS YOU
