A visual example of this is one my mother showed me. She drew a circle and laid out a piece of yarn around it so that it imitated the perfect shape of the circle. She laid out another piece that was as long as the circle's radius. She wrapped the longer piece around the shorter one, and I saw that it could wrap around it three times and still have at least 0.14 units left. I'm not sure if this helps, but the circumference of this circle is 18.84 cm ^2. I hope I answered your question.
Answer:
Width: 6 cm
Length: 9 cm
Step-by-step explanation:
Width: x
Length: x + 3
2(x)+2(x+3) = 30cm
2x + 2x + 6 = 30
4x = 30-6
x = 24/4
x = 6
The perimeter of the rectangle:
The perimeter of the square:
The perimeter of the rectangle is equal to the perimeter of the square. We have the equation:
The side lengths of the square:
The side lenghts of the rectangle:
Other method.
If the first figure is a square, then the length of the sides are equal.
Therefore
Further part of the solution as above.
Answer:
X= 4
Step-by-step explanation:
28 = 4(x+3)
7 = x+3
x = 4
