What is the perimeter of 12 cm?
Ah, the perimeter is like a warm hug around a shape, adding up all the sides together. For a shape with sides of 12 cm each, the perimeter would be 12 cm + 12 cm + 12 cm + 12 cm, which equals 48 cm. Just imagine those sides coming together in a peaceful harmony, creating a perfect boundary.
What is the perimeter of 4 centimeters by 2 centimeters rectangle?
The answer is 12 cm.
If a square has a side of 3cm what is perimeter?
Perimeter of a square = 4*side = 4*3 cm = 12 cm.
What is the cross sectional area of a cube with a perimeter of 48cm?
A perimeter is normally defined for 2-dimensional shapes and not three dimensional ones. A cube has 12 edges. So, if the perimeter is 48 cm, each edge must be 48/12 = 4 cm. The cross section of a cube depends on the angle of the plane intersecting the cube and, if it is not perpendicular to the cube, can be triangular, parallelogram or hexagonal. Assuming the plane is at right angles to the cube, the cross section is a square with sides of 4 cm. So its area is 16 cm2
Can two shapes have the same area and different perimeters?
Yes Example: Rectangle A has an area of 64 cm. and a perimeter of 32 8 cm. by 8 cm. Rectangle B has an area of 64 cm. and a perimeter of 40 4 cm. by 16 cm
