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:
Perimeter = sum of length of all sides = 8 + 3 + 10 + 11 = 32
Area = (base1 + base2) x height/2 = (3 + 11) x 7/2 = 49
Hope this helps!

R = 24.4 / 2 = 12.2
A = 3.14 (12.2)^2
A = 3.14 (148.84)
A = 467. 36
hope it helps
The answer is 6, because 8-2=6 ; 14-8=6 ; 20-14=6 and so on.
