Question

The area of a rectangular garden is 256 square meters. List all possible whole number dimensions that the garden can have.

Answer 1

The dimensions of the garden can be found by finding the factor pairs of the number 256.
The various factor pairs of 256 are as follows:
256 = 1 $\times$ 256
256 = 2 $\times$ 128
256 = 4 $\times$ 64
256 = 8 $\times$ 32
256 = 16 $\times$ 16

$\therefore$ The various dimensions of the garden can be, (1, 256),(2, 128),(4, 64),(8, 32), and (16, 16).
