As we know perimeter of rectangle = 2(l+b)
= 2(5x+4+x-4) = 72
= 2(6x) = 72
12x = 72
x = 6
Length = 5x+4 = 34
Breadth = x-4 = 2

If perimeter is 72m, then half the perimeter will be 36m,i.e, length plus breadth = 36m
A/Q,
l + b = 36m
=> 5x + 4 + x - 4 = 36m
=> 6x = 36m
=> x = 36/6m
=> x = 6m
Now,
Length of rectangle = 5x+4
= 5(6) + 4
= 30 + 4
= 34m
And,
Breadth of rectangle= x-4
= 6-4
= 2m
Hope that helps
