Answer:
A = 325(1.07)^1
Step-by-step explanation:
first one shows an increase of 70%
second one shows a decrease of 7%
Last shows a decrease of 93%
<span>2 2/3 + 4/5
= 8/3 + 4/5
= 40/15 + 12/15
= 52/15

W - a width
3w - a length
27 ft² - an area
Therefore:
w · 3w = 27
3w² = 27 |:3
w² = 9 → w = √9 → w = 3
3w = 3 · 3 = 9
width = 3
length = 9
The perimeter:
P = 2 · width + 2 · length
P = 2 · 3 + 2 · 9 = 6 + 18 = 24 ft.
