Question 830381
<pre>
Hi, there--

Let A be the area of the rectangle.
Let B be its base.
Let H be the height.

The most common formula for the area of a rectangle is 
{{{A = B * H}}}

We can rewrite this in "base equals" form by dividing both sides by H.

{{{A/H = (B*H)/H}}}

The H is the numerator and denominator on the right side cancel each other because H/H=1.
{{{A/H = B*cross (H)/cross (H)}}}
{{{B=A/H}}}

In other words, to find the base, divide the area by the height.

Hope this helps,
Mrs. F
