Answer:
OR
Step-by-step explanation:
So first you find the difference between the new cost and the old cost:
450 - 370 = 80
So the increase was 80.
When you write it as a fraction you write the increase ( 80 ) over the starting cost ( 370 ).
Thus the answer becomes
But you can always reduce it to its lowest terms thus:

Set the width to be x. Thus, the length is 4x.
The perimeter is 2(x+4x)=100, so x=10.
Plugging in x=10, you get that 4x=40.
So, the area of the rectangle is 400 .
Because there are 100 centimeters in a meter and you are asking for area, you must multiply by to get 4000000
