Correlation analysis seeks to establish whether or not two variables are correlated. That is to say, whether an increase in one is accompanied by either an increase (or decrease) in the other most of the time. It is a measure of the degree to which they change together. Regression analysis goes further and seeks to measure the extent of the change. Using statistical techniques, a regression line is fitted to the observations and this line is the best measure of how changes in one variable affect the other variable. Although the first of these variables is frequently called an independent or even explanatory variable, and the second is called a dependent variable, the existence of regression does not imply a causal relationship.
It gives a measure of the "flatness" of the rectangle. It is not a measure which is used to any significant extent.
Area is a measure of the extent of a shape in two dimensional space.
A variable is a symbol that represents one or more numbers.
An area is a measure of the extant of a surface, measured in square units, a particular geographic region, or an extent of surface.
Correlation.
Correlation is a statistical measure that indicates the extent to which two or more variables fluctuate together. A positive correlation indicates the extent to which those variables increase or decrease in parallel; a negative correlation indicates the extent to which one variable increases as the other decreases.
The term you are looking for is "correlation." This refers to a statistical measure that indicates the extent to which two or more variables fluctuate together. A positive correlation means the variables move in the same direction, while a negative correlation means they move in opposite directions.

Heritability is the statistical estimate of the proportion of the total variance in a trait that is attributed to genetic differences among individuals within a group. It provides a way to quantify the extent to which genetic factors contribute to individual differences in a specific trait within a population.
