Question : the diagram shows a plan for creating a zoo’s elephant exhibit. the elephant pen will be surrounded on two sides by a walkway with a viewing area in one corner. the sides, shown as dotted lines, will be fenced. how much fencing separates the elephant area from the walkways

answer choices :

(a) 180 feet
(b) 250 feet
(c) 540 feet
(d) 750 feet

C

Step-by-step explanation:

We need to find the length of the red dotted line.

It is divided into 3 parts: the top, the middle slant, and the bottom

The top

Goes from y = 50 to y = 120, the length is:

120 - 50 = 70 units

The bottom

Goes from x = 60 to x = 120, the length is:

120 - 60 = 60 units

The middle slant

This is hypotenuse of the right triangle shown.

We will use Pythagorean Theorem to solve for this length, let it be x.

The theorem is:

Leg^2 + Another Leg^2 = x^2

One leg goes from x = 20 to x = 60, the length is 60 - 20 = 40

Another leg goes from y = 20 to y = 50, the lenth is 50 - 20 = 30

So, we have:

THe slant length is 50 units

TOtal fencing is:  70 + 60 + 50 = 180 units

1 unit is 3 feet, so

180 units * 3 = 540 feet

C is the correct answer
