Let w be the width
Then the length is 2w - 2
We also know that the perimeter is 62 cm. The perimeter is the distance around the rectangle, or 2w + 2(2w - 2).
So, 2w + 2(2w - 2) = 62
2w + 4w - 4 = 62
6w = 66
w = 11
So, the length is 2w - 2 = 2(11) - 2 = 22 - 2 = 20
Length = 20 cm
Width = 11 cm
There are an infinite number of shapes, because a shape can have any number of sides. This is where we get into our laws of fractals. A fractal is a shape with an infinite perimeter and area, meaning that every level of infinity is another shape, but can be beat by another shape. However, this is all philosophical math and goes way beyond the context of your question.
To keep it short and simple, there are an infinite number of shapes in the world.
Answer:
1674.66 cm^3
Step-by-step explanation:
V=πr^2 (h/3)
so v= π8^2 (25/3)
v=1674.66
