The area of the rectangle calculate using the algebraic model given is 84 m²
<u>Given the algebraic representation </u><u>for</u><u> </u><u>the area of a rectangle</u> :
- Area of rectangle = 6x² + 9x + 3
<u>The Area of the rectangle when x = 3 can be calculated thus</u> :
Substitute the value x = 3 into the equation :
x = 3
Area of rectangle = 6(3)² + 9(3) + 3
Area of rectangle = 54 + 27 + 3 = 84 m²
Therefore, the area of the rectangle is 84 m²
