Verified answer
The area of a rectangle is (x² – 121) square units while its width measures (x+11) units. The length of the rectangle is (x - 11) units.
Algebra is a part of mathematics including number theory, geometry, and analysis of its solutions.
Algebraic form is a technique used to present a mathematical problem with symbols or letters as variables of an object in the problem.
General terms that need to be known to understand the form of an algebra include equations, variables, coefficients, constants, exponents, degrees, and terms.
Algebraic operations are generally almost the same as integer arithmetic operations.
1. Algebraic Addition and Subtraction Operations
Algebraic addition and subtraction operations can only be performed on like terms.
2. Algebraic Multiplication Operations
3. Algebraic Division Operation
To simplify the algebraic division operation, it is done by converting it to fraction form.
Rectangle Area Formula
The Area = the length × the width
Step-by-step explanation:
Given:
The area of a rectangle is (x² – 121) square units.
The width measures (x + 11) units.
Question:
Illustrate a rational algebraic expression in finding the length of the rectangle.
Solutions:
The Area = the length × the width
(x² – 121) = the length × (x + 11)
The length =
The length =
The length = (x - 11)
So, illustrate a rational algebraic expression in finding the length of the rectangle is (x - 11) units.
