Ryan measure the perimeter of his square painting so he can make a wooden frame . find the perimeter of the painting in centimet
ers remember the formula for perimeter is p equals 4 * s
1 answer:
Answer:
Perimeter = 122 cm or 1.22 m
Step-by-step explanation:
The complete question with image is attached.
We know the perimeter is the sum of all the sides.
Since it's already given that one side is 30.5 and we know it is a square, so perimeter would be sum of all the 4 sides [each 30.5 cm].
Perimeter = 30.5 + 30.5 + 30.5 + 30.5 = 122 cm
Also, to get the answer in meters, we need to know that 100 cm = 1 m, hence
We got to divide by 100 to get our answer in meters, so
122/100 = 1.22 meters
Hence
Perimeter = 1.22 m

By using some logic and the formula of the triangle's area, we will find that the smallest possible area is 12.5 cm²
How to start thinking about the problem.
First of all, for the configuration of this paper strip, we can see that the base of the triangle will <u>always be equal of the width of the paper</u>. Thus, the smallest area will be only dependent of the height of the triangle.
Now, we need to analyze the picture to figure out how we can get the smallest height possible for that triangle.
What is the smallest height possible.
Doing this, we shall see that the smallest height possible is actually when the height equals the width itself, as it's shown in the attached image.
How to calculate the smallest area possible.
Thus, to calculate the smallest area, we just have to use the formula of the area of the triangle, which is <em>, where </em><u><em>b is the base</em></u><em> and </em><u><em>h is the height</em></u><em>.</em>
As we previously found, for this question, the
<em>base = height = width of the paper = 5cm</em>
Now, we just have to calculate it with the formula
