Answer: The length of the rectangle is 13.5 units and the width is 4.5 units

Step-by-step explanation: The perimeter of the rectangle has been given as 36 units. The formula applied to calculate the perimeter is

Perimeter = 2(L + W)

However the details in the question states that the rectangle is three times as long as it is wide. That is, the length is three times it’s width. So if the width is W then the length is 3W.

Therefore, to calculate the perimeter we shall apply the following;

Perimeter = 2(3W + W)

If the perimeter is given as 36 units, then we have;

36 = 2(4W)

We cross multiply and we have

36/2 = 4W

18 = 4W

Divide both sides of the equation by 4

4.5 = W

So the width is calculated as 4.5, hence the length would be 3W which equals 3 x 4.5 and that equals 13.5

Therefore, Length = 13.5 units and Width = 4.5 units

The bearing from the Pine Knob fire tower to the Colt Station fire tower is N 65° E, and the two towers are 31 kilometers apart.
suter [353]

The distance are

a. 42.42

b. 15. 52

<h3>How to solve for the distance</h3>

80 = 65 + <ABC

<ABC = 80 - 65

= 15

Through the use of sine rule we would have

By using sine rule,

Sine 15/a = sine 135/b =

sin 30/30.

Next we have to solve b by cross multiplying

b = (30× sin135) / sin 30

= 21.21/0.5

b = 42.42 km

Also, the value of a will be:

= (42.42 × sin 15) / sin 135

= 10.98/0.7071

= 15.52
