How to draw a shape with a perimeter that is 12 or 15 or 18 or 21 and the area is 12?
The perimeter and area of a shape do not provide sufficient information. With a given perimeter, the largest area that you can enclose is a circle, but you can then flatten the circle to reduce its area. Similarly, in terms a of quadrilaterals, a square has the largest area, but it can be flexed into a rhombus whose area can be made as small as you like. All that can be said is that there is no shape with a perimeter of 12 units whose area is 12 square units.
What is the shape for a figure to have a perimeter of 20 and an area of 18?
Perimeter and area are not sufficient to determine the shape of a figure.
What is a complex shape with an area of 100cm and a perimeter of 30cm?
There is no such shape. Firstly, because no shape can jave an area of 100 cm. Suppose, though, that its area were 100 SQUARE cms, even then, there is no possible solution. Of all the shapes possible with a given perimeter, a circle has the greatest area. A perimeter of 30 cm means a radius of 30/(2*pi) = 15/pi cm. A circle with this radius would have an area of pi*(15/pi)2 = 225/pi = 71.62 sq cm : well below the area required.
What is area an perimeter?
Area is the amount of square units in a 2-D shape, and perimeter is the distance around a shape
Which shape has the largest area per perimeter?
In other words ... least fence for greatest area ... First place . . . Circle Second place . . . Square
