Answer:
7
Step-by-step explanation:
Area is found by multiplying the length and the width.
Let's think about the factors of 56.
The only <em>whole number pairs</em> that can be multiplied to get 56 are
1 x 56, 2 x 28, 4 x 14, and 7 x 8.
There's only one pair where the width is less than the length, 7 x 8.
The width is always the smaller number of the two, so the width must be 7.
