Step-by-step explanation:
Given that:
Length of a rectangle =
Width of rectangle =
To find:
Simple polynomial expression for finding the area of rectangle.
Solution:
First of all, we should know about the formula for finding the area of rectangle. Then we should know how to multiply two polynomials.
Formula for area of a rectangle in terms of its length and width is:
Putting the given values:
Here, we can use the distributive property of multiplication for finding the value of the above multiplication expression.
Therefore, the multiplication of above polynomials can be written as:
Therefore, the answer is:
