To determine how many different rectangles can be formed, you need to know the number of horizontal and vertical lines available. The formula for calculating the number of rectangles is based on choosing two horizontal lines and two vertical lines from the grid. If there are ( m ) horizontal lines and ( n ) vertical lines, the total number of rectangles is given by the combination formula: ( \binom{m}{2} \times \binom{n}{2} ). This accounts for all possible pairs of lines that can create a rectangle.

How many rectangles of different sizes can be formed from 36 identical squares?
To determine how many rectangles of different sizes can be formed from 36 identical squares, we first need to find the possible dimensions of rectangles that can be created using these squares. The total area of the rectangles must equal 36, which can be expressed as ( length \times width = 36 ). The pairs of factors of 36 are (1, 36), (2, 18), (3, 12), (4, 9), and (6, 6), leading to 10 unique rectangles when considering both orientations (length × width and width × length). Thus, a total of 10 different rectangles can be formed.
How many rectangles can you build with 8 squares?
Squares are actually also rectangles so you could make 8 rectangles without touching any of the squares. However, if you could cut the squares, that would be a different problem....

How many different rectangles can you make from 12 squares?
Assuming the 12 squares are the same size, three. And three more if you count different orientations (swapping length and breadth) as different rectangles.

Infinite amounts.
Names of quadrilaterals?
There are many different quadrilaterals such as squares, trapezoids, rectangles, rhombus and parallelogram.
Are all rectangles similar?
No not all rectangles are similar because the proportions are different.
How many different rectangles with an area of 12 square units can be formed using unit squares?
3 or 6, depending on whether rectangles rotated through 90 degrees are counted as different. The rectangles are 1x12, 2x6 3x4 and their rotated versions: 4x3, 6x2 and 12x1.
