The area of original square is 16 centimetre square.
The area is the region bounded by the shape of an object.
Let consider 'a' as the side of the original square.
When it fold vertically then the top and bottom sides will be half of the original side.
The perimeter of folded square = 12 cm
i.e. (2* 0.5a)+ 2a =3a =12 cm
Then, a=4cm
The area of original square is given by a^2.
Then, a^2 = 4*4 =16
Hence, 16 centimeter is the area of the original square.

Answer:
improper fraction
Step-by-step explanation:
Improper fractions are fractions that have a larger numerator than denominator like in this case.
Example:
Mixed numbers contain a whole number and a fraction.
Example:

Proper fractions are fractions that have a larger denominator than numerator.
Example:
The altitude of the equilateral triangle with sides 6√3 meters is 9 meters.
The length of the sides are 6√3 meters each. Recall triangles has three sides.
Therefore, the altitude or height of the triangle can be found as follows:
Using Pythagoras theorem,
c² = a² + b²
where
c = hypotenuse
a and b are the other 2 legs.
Therefore,
h² = (6√3)² - (1 /2 (6√3))²
h² = 108 - 27
h = √81
h = 9 meters
Therefore, the altitude of the triangle is 9 meters.
