1 answer:
The expression 21x⁴ + 56x³ + 49x² represents the area of the entire rectangle.
<h3>What is the area of the rectangle?</h3>It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The area of the rectangle = length x width
= (3x² + 8x + 7)(7x²)
= 21x⁴ + 56x³ + 49x²
Thus, the expression 21x⁴ + 56x³ + 49x² represents the area of the entire rectangle.
