Software programs called database management systems (DBMS) are used to store, retrieve, and query data. Users can add, read, edit, and delete data from databases using a database management system (DBMS), which acts as an interface between an end-user and the database. DBMSs control the data, the database engine, and the database structure, enabling users and other applications to extract or modify the data. It also contributes to concurrency, uniform data management practices, and data security. The normalization technique, used in database schema design, allows DBMS to optimize the arrangement of data by dividing large tables into smaller ones when any of their properties have redundant values.

The typed page is 2.5 by 2.5 inches. For objects with two or more dimensions, area is calculated. The area of one-dimensional objects is not calculable.
Any non-negative real integer can represent an area. Integrals are frequently applied while assessing area. It is well known that the product of a rectangle's dimensions determines its area. Let the paper page's area and the typed page's area be AT and AP, respectively. If the typed page is x characters long, we get AT=x5 and AP=46.
The answer to the query is AT=1/2AP.
So, ascertain x's value.
