Legnth of the sides and then you add them up to get the perimeter
You need more information. There are many shapes which could hold the same volume, but have different (is it perimeter of the base, maybe?).
You don't. Perimeter is a concept associated with plane figures, not solid shapes.
You don't need to if you can manage to work out the perimeter and area of complex shapes. Most people cannot work easily with shapes other than triangles, quadrilaterals, circles and semicircles. For them (us) it is easier to partition the shape.
They are the result of combining shapes, either by adding parts or taking parts away. We calculate the perimeter of composite shapes by splitting them into simpler pieces and then calculating the perimeter of those simpler pieces.
To calculate the perimeter when you only know the area, you need additional information about the shape of the figure, as different shapes can have the same area but different perimeters. For example, if you assume a specific shape like a square, you can use the formula for the area (A = side²) to find the side length, then calculate the perimeter (P = 4 × side). If the shape is not specified, the perimeter cannot be uniquely determined from the area alone.
no No. You need to know the length of a rectangle's sides in order to calculate the perimeter.
It is called the perimeter. How you calculate it depends upon the type of shape it is.
There are many shapes for calculating perimeter such as:Rectangle: 2(L+W) where L=length and W=weightSquare: 4s where s=# givenTriangle and most shapes: add up all the sidesCircle: 2∏r
it means make same shapes only perimeter
To find the perimeter of two-dimensional shapes, add the lengths of all the sides together. The sum is the perimeter of the figure.
To create a working model on perimeter, start by selecting various geometric shapes, such as squares, rectangles, and triangles. Measure the lengths of their sides and calculate the perimeter using the formula (sum of all sides) for each shape. Use materials like cardboard or foam to construct the shapes, and label each side with its measurement. Finally, present your model by explaining the concept of perimeter and demonstrating how to calculate it for each shape.
For the area of a square, it is the base x the height, and the perimeter is 2height+2base. For the area of a triangle, it is base x height divided by two. And to find the perimeter you just add up each of the side lengths.
