To re-phrase this: 50 is a certain percent of 90.
this can be written mathematically as 50=x%*90
let's divide both sides by 10:
5=x%*9
and divide both sides by 9:
which in decimals is approximately 0.56 (but not exactly).
so 0.56=x%
and the x then 56
so 50 is approximately 56% of 90:
exactly 56%of 90 is 50.4
this can be written mathematically as 50=x%*90
let's divide both sides by 10:
5=x%*9
and divide both sides by 9:

To solve this problem, we have to use the area of both gauze or the dimensions on each gauze and compare them. we can see that the sheets are not similar as they have different areas.
<h3>Area of Rectangle</h3>The area of a rectangle is given as the product between the length and it's width.
Data;
- Length = 9in
- Area = 45in^2
- width = ?
- length 2 = 4in
- width 2 = 3in
In the first gauze, the area is given as 45in^2 and we have value of the length. To find the width of the first gauze can be calculated as
We can see that the width are not equal so is their length.
But if we would truly compare them, the accurate way to do that is by their area
The area of the second gauze is given by
From the above calculations, we can see that the sheets are not similar as they have different areas.
