Answer:
39 ft
Step-by-step explanation:
Using the description as a guideline I have drawn out the situation (badly drawn) as seen in the picture below. From the picture, we see that we need to find x which is the length of one of the ropes. Once we have this length we simply multiply it by 3 to find out how much rope we need altogether. Since this is the diagonal of a triangle we can use the Pythagorean theorem to solve for x.
Pythagorean theorem: 
.... which a and b are the two sides while x is the diagonal.
... now we square root both sides
Now that we have the length of one of the ropes we simply multiply this by 3 to find the total amount of rope needed.
13 * 3 = 39 ft

Answer:
Current deposit amount = $324.65 (Approx.)
Step-by-step explanation:
Given:
Cost of bicycle = $400
Future amount = $400
Rate of interest = 11% = 0.11
Number of year = 2 year
Find:
Current deposit amount
Computation:
Compound interest formula
A = P[1+r]ⁿ
Future amount = Current deposit[1+Rate of interest]ⁿ
400 = Current deposit[1+0.11]²
400 = Current deposit[1.11]²
400 = Current deposit[1.2321]
Current deposit amount = 400 /1.2321
Current deposit amount = $324.65 (Approx.)

Here!
(x+4)+(x+2)+(x+5)= (x+1)+(x+1)+(x+3)+(x+3)
First you want to write the whole equation out. Make each perimeter equal to each other.
Then add both sides separately.
(x+4)+(x+2)+(x+5)
=3x+11
and
(x+1)+(x+1)+(x+3)+(x+3)
=4x+8
Now that you've simplified each side, solve like a normal equation.
3x+11 = 4x+8
-3x -3x
11 = x+8
-8 -8
3=x
