There are infinitely many of them. The square of any multiple of four that is greater or equal to 12 will meet the requirement.
It has 4 and they all meet at right angles which is 90 degrees
An acre is a measure of area. It does not have to be rectangular in shape. And, given only the area, there are infinitely many configurations of length and breadth that will meet the requirements of the question.
A Rectangle!
One, though it's technically a square - hence why it is called a square pyramid. By definition, a square pyramid has one square face. It also has four triangular faces which meet at the apex (the tip) of the pyramid.
There are infinitely many of them. The square of any multiple of four that is greater or equal to 12 will meet the requirement.
A square is one type of rhomboid that meets the criteria of four equal sides. If the angles are not all equal there are many diamon shaped figures which meet the criteria.
A rectangle is a plane four sided shape. It has two pairs of parallel sides which meet at right angles. So is a square. The opposite sides of a rectangle are equal but in a square all four sides are equal. So a square is a rectangle but a rectangle is not a square.
A square is a closed plane figure bounded by 4 straight lines which are of equal length and which meet one another at right angles. Anything else is non-square.
Four of them
A square can be any size. The only rule is that for it to a perfect square, all 4 sides should be of equal lengths and meet each other at right angles (90 degrees).
The centre of the square is where the two diagonals meet. Take any point on the boundary of the square. Draw a straight line from that point , through the centre of the square, to the other side of the square. This line divides the square into two halves of identical shape and size. Since there are infinitely many points along the side of the square, there are infinitely man solutions.

A regular quadrilateral. A plane shape with four sides which are equal in length and which meet at right angles.
A square pyramid is a polyhedron with a square base and triangular sides that meet at a point at the top. This gives this pyramid five faces.
