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:
23.39% off.
Step-by-step explanation:

= 0.2339 * 100
= 23.39%.
Answer: -3
Step-by-step explanation:
First... Distribute the -3 into x and -8. You'll have -3x + 24 + 7x = 12
Next... Subtract 24 on both sides (-3x + 24 - 24 + 7x = 12 - 24)
-3x + 7x = -12
Add like terms to get 4x = -12
Finally.. you divide 4 on both and you have...
x = -3
