All 4 sides of a square are the same length.
If the perimeter of the square is 20-ft, then each side is 20-ft/4 = 5 ft.
If you increase the length of the square by 2-ft, then its new length is 5+2 = 7-ft.
If you decrease the width of the square by 1-ft, then its new width is 5-1 = 4-ft.
The area of the new figure is (length) x (width) = (7-ft x 4-ft) = <u>28 square feet</u>.
Using proportions, supposing a scale of 1 inch = 3 feet, the actual measurements of her bed are given by: 9 ft x 18 ft.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations such as multiplication or division, from the relations built in the problem.
One example of application of proportions is for scale problems, as the actual scale and the drawing length are compared to find the actual length of the object drawn.
In the context of this problem, the scale is given by:
1 inch = 3 feet.
The drawn length of the bed is given by:
3 inches x 6 inches.
Hence the actual length is given by:
9 feet x 18 feet.
As:
<h3>What is the missing information?</h3>
The scale of the drawing is missing, hence we are going to suppose that it is 1 inch = 3 feet.

Eva follows the bond market and often purchases bonds issued by Sanden Research Labs. Last year, she purchased three such bonds in January, one in May, and four in June, then sold them all in November. Sanden Research Labs bonds were selling at 78.430 in January, 95.652 in May, 86.220 in June, and 87.454 in November. If each bond she purchased had a par value of $500, how much profit did Eva gain from buying and selling these bonds?</span>
You can tell that the equal share is more than 1 whole when the numerator is greater than the denominator.How? As we all know that in order to convert a fraction to a decimal number, we need to divide the numerator by the denominator.Now, if the numerator is less than the denominator, expect that the digit is now less than 1 whole. But if the numerator is greater than the denominator, for sure, it is more than 1 whole for example.=> 5/4 , where 5 is the numerator and 4 is the denominator<span>=> 1 and 1/4 or 1.25</span>
