Answer:
Speed of the river =
km per hour
Step-by-step explanation:
Speed of the boat in still water = 4 km per hour
Let the speed of the river = v km per hour
Speed of the boat upstream = (4 - v) km per hour
Time taken to cover 6 km = 
=
hours
Speed of the boat downstream = (4 + v) km per hour
Time taken to cover 12 km =
hours
Since, time taken by the boat in both the cases is same,

6(4 + v) = 12(4 - v)
24 + 6v = 48 - 12v
12v + 6v = 48 - 24
18v = 24
v = 
v =
km per hour

Answer:
The Answer is: Perimeter = 39.12
Step-by-step explanation:
Given: area is 56.96 m^2
Given: length is 16m.
Find Width.
Equation:
Length x Width = Area
Solve for Width, w.
16 x w = 56.96
w = 56.96/16 = 3.56.
Perimeter all the sides added together:
P= 2l + 2w
= 2(16) + 2(3.56)
= 32 + 7.12
= 39.12 m, perimeter
