Question

Can a square number be a rectangular number ? Give example

Answer 1

Step-by-step explanation:

For example, 72=49 is a square number. For example, 2×18 is a rectangular number that also happens to be a square number, though you'd have to rearrange it as 6×6 to fit in the square. A number like 40, on the other hand, is rectangular but not square, as you can arrange it 2×20, 4×10 or 5×8, but √40≈6.32.
