Using the area of a rectangle, it is found that her patio should have a width of 12 feet and a length of 27 feet.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given by:
A = lw.
In this problem:
- She has enough tiles to cover 324 square feet, hence A = 324.
- She wants the length of the patio to be 15 feet longer than the width, hence l = 15 + w.
Thus:
324 = w(15 + w)
w^2 + 15w - 324 = 0
w = -27 or w = 12.
We take the positive value, hence l = 15 + w = 15 + 12 = 27 feet.
The dimensions should be a width of 12 feet and a length of 27 feet.

Answer:
The number of packages of gift wrap and greeting cards sold is 181 and 44 respectively
Step-by-step explanation:
The computation of the number of packages of gift wrap and greeting cards sold is as follows:
Let us assume the number of packages of gift wrap be x
And, for greeting cards be y
The equation are as follows
x + y = 225 ..................(1)
We can write as
y = 225 - x
4x + 10y = $1,164 ............(2)
Now put the y value in the equation 2
4x + 10 (225 - x) = $1,164
4x + $2,250 - 10x = $1,164
-6x = $1,164 - $2,250
-6x = -$1,086
x = 181
And, y = 225 - 181
= 44
