Answer:

b = 3.5 cm

Step-by-step explanation:

Given that,

The area of a rectangle, A = 14. sq cm

The length of one side, l = 4 cm

We need to find the length of another side. The formula for the area of a rectangle is given by :

A = lb

So,

$14=4b\\\\b=\dfrac{14}{4}\\\\b=3.5\ cm$

So, the length of the other side is equal to 3.5 cm.
