ray is constructing a flowerbed for the zoo and wants to know if he has enough edging. a sketch of the flowerbed is shown below. what is the perimeter of the triangle? round to the nearest whole number.
12 ft
12 ft
41 ft
48 ft
24 ft
72 ft

Explanation:

Step1: Find hypotenuse length

Use Pythagorean theorem: $c = \sqrt{a^2 + b^2}$ where $a=12$, $b=12$.
$\sqrt{12^2 + 12^2} = \sqrt{144 + 144} = \sqrt{288} \approx 16.97$ ft

Step2: Calculate total perimeter

Add all three sides: $12 + 12 + 16.97$
$12 + 12 + 16.97 = 40.97$ ft

Step3: Round to nearest whole number

Round 40.97 to the closest integer.
$40.97 \approx 41$ ft

Answer:

41 ft
