Length (L): L
width (w): (2/3)L
Perimeter (P) = 2L + 2w
390 = 2(L) + 2(2/3)(L)
1170 = 6L + 4L
1170 = 10L
117 = L
width (w): (2/3)L = (2/3)(117) = 2(39) = 78
Answer: width = 78 ft, length = 117 ft
Answer:
5 is your answer
Step-by-step explanation:
The 
will equal to 5, because 
= 25
Oh, this is easy. For any prism, you find the surface area by finding the are of all the sides. I will post all surface area formulas here, for reference
Cube:
Surface area = 6 × a2
Right circular cylinder:
Surface area = 2 × pi × r2 + 2 × pi × r × h
pi = 3.14
h is the height
r is the radius
Rectangular prism:
Surface area = 2 × l × w + 2 × l × h + 2 × w × h
l is the length
w is the width
h is the height
Sphere:
Surface area = 4 × pi × r2
pi = 3.14
r is the radius
Right circular cone:
Surface area = pi × r2 + pi × r ×( √(h2 + r2))
pi = 3.14
r is the radius
h is the height
l is the slant height
Right square pyramid:
Surface area = s2 + 2 × s × l
s is the length of the base
h is the height
l is the slant height

Define their percentage:
----------------------------------
Adam = 100%
Tapiwa = 100 + 5 = 105%
----------------------------------
Find their total percentage:
----------------------------------
100 + 105 = 205
----------------------------------
Find 1%
----------------------------------
205% = 697 liters
1% = 3.4 liters
----------------------------------
Find 100% (Adam):
----------------------------------
100% = 3.4 x 100
100% = 340 liters
----------------------------------
Find 105% (Tapiwa):
----------------------------------
105% = 3.4 x 105
105% = 357 liters
--------------------------------------------------------------------
Answer: Tapiwa = 357 liters and Adam = 340 liters.
