Answer: length of the rectangular firls = 50
and the breadth = x-20m= 50-20m =30m
Step-by-step explanation:
The perimeter of a rectangle is given as 2(l+b)
let the length be represented as x
such that the breadth = x-20m
so our expression for the perimeter of the rectangular firls becomes
Perimeter = 2l+ 2b
160= 2x + 2 ( x-20)
160= 2x+ 2x-40
160+40 =4x
200= 4x
x= 200/4
x= 50
So the length of the rectangular firls = 50
and the breadth = x-20m= 50-20m =30m
Answer:
Length =60m
Breadth= 20m
Step-by-step explanation:
Breadth of the rectangular firls = 20m
Perimeter = 160m
Length = X
Perimeter of a rectangle = 2(L +B)
Where L= Length
B = Breadth
160 = 2( 20 + X)
160 = 40 +20X
160- 40 =20X
120= 20X
20X = 120
X = 120/20
X = 60
The dimensions are:
Length =60m
Breadth= 20m
