Are the products of opposite corners of any rectangle in the multiplication table equal?
Yes.
Why does it makes sense that the products of opposite corners of any rectangle in the multiplication table are equal?
Consider the rectangle in a multiplication table where the left side of the rectangle is in the column for p times table; the right side of the rectangle is in the column for q times table. Also suppose the top of the rectangle is in the row for the r times table and the bottom of the rectangle is in the row for the s times table.Schematically,----p------q----|-------|r---a-----b----|------|----|------|s--c-----dSuppose the numbers in the four corners of the rectangle are a, b, c and d.Thena = pr, b = qr, c = ps and d = qsSo the product of opposite corners aread = pr x qs = pqrsbc = qr x ps = pqrs

How do you multiply 507x49 equals?
To multiply 507 by 49, you can use the standard multiplication method. First, multiply 507 by 9, which equals 4,563. Then, multiply 507 by 40 (which is 49 with the zero), resulting in 20,280. Finally, add these two products together: 4,563 + 20,280 = 24,843. Therefore, 507 x 49 equals 24,843.
How can you find the perimeter of a rectangle if you know its length and width?
The formula for perimeter is 2l+2w or 2*length + 2*width. This means that you multiply the length by two and multiply the width by two. Then, you add the two products together to find the perimeter.
