Answer:

[tex] \therefore [/tex] The area of the rectangle is [tex] b^2 + 9b + 18 [/tex]

Step-by-step explanation:

To get the area of the rectangle. We must use the formula when finding area of rectangle.

  • [tex] A = lw[/tex]

Where:

  • A is the area
  • l is the length
  • w is the width

We're going to do is multiply the length to width to get the product. The product of the length and width will be the area of the rectangle.

Substitute the given to formula.

[tex] A = (b+6)(b+3) [/tex]

[tex] A = bb + b \cdot 3 + 6b+6\cdot 3 [/tex]

[tex] A = bb + 9b + 6 \cdot 3 [/tex]

[tex] A = b^2 + 9b + 18 [/tex]

[tex] \therefore [/tex] The area of the rectangle is [tex] b^2 + 9b + 18 [/tex]
