5d + 2(2 - d) = 3(1 + d) + 1
5d + 2(2) - 2(d) = 3(1) + 3(d) + 1
5d + 4 - 2d = 3 + 3d + 1
5d - 2d + 4 = 3d + 3 + 1
3d + 4 = 3d + 4
-3d -3d 
 4 = 4
 d = 0

ioda

The area of the rectangle calculate using the algebraic model given is 84 m²

Given the algebraic representation for the area of a rectangle :

Area of rectangle = 6x² + 9x + 3

The Area of the rectangle when x = 3 can be calculated thus :

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
