200
Let width = x
Let length = 2x
Let’s area = a
x+2x+x+2x=60
Combine the terms
6x = 60
Divide both sides by 6
x = 10
Width = 10
Length = 2*10 = 20
Area = 10*20 = 200
Again set a proportion
x/4=35.25/1
=x=4(35.25)
x=141
Therefore the boat traveled 141 kilometres.
The answer is C.
The equation of a circle is written as (x-h)^2 +(y-k)^2 = r^2
h is the x value of the center and k is the y value of the center and r is the radius.
Replace h, k and r with the given information:
(x- -7)^2 + (y - -6)^2 = 4^2
Simplify:
(x+7)^2 + (y+6)^2 = 16
