The perimeter is 7 cm
The perimeter of a rhombus is the sum of its 4 sides
If it has 2 opposite parallel sides of 10 cm and 2 opposite parallel sides of 5 cm then its perimeter is the sum of the 4 sides which is 30 cm
Perimeter = 5*5 = 25 cm
6+4+6+4=20 cm
Assuming by "equal" you mean that each side is 5 cm, then the perimeter of a square is 5 cm * 4 (sides) = 5 cm + 5 cm + 5 cm + 5 cm = 20 cm The perimeter of any polygon is the sum of the sides Alternatively if by "equal" you mean the sides sum to 5 cm, then the perimeter is 5 cm. Although this is probably not what you meant =)
It is not. The perimeter of a 1 cm square is 4 cm. The perimeter of a 5 km * 15 km rectangle is 4000000 cm: a million times as large!
The area of square is : 400.0
Each side = 20/4 = 5 cm Area = 5*5 = 25 square cm
20 cm/5 = 4 cm
Since it is a square, all four sides are the same. The side is sqrt(25 cm2) = 5 cm. The perimeter is 4 x 5 cm = 20 cm.
The perimeter is all of the sides added together. So 4+4+4+4 is 16. The perimeter is 16cm.
3 cm, 4 cm and 5 cm because they are a Pythagorean triple
square has four sides 4 (sides) x 5 (cm) 4 X 5 = 20cm
The perimeter is 7 cm
The dimensions of the rectangle are 5 cm by 4 cm
The answer is 12 cm.
