Question

Write an expression for the area of this

rectangle. Expand your expression so
that your answer does not contain
brackets.
_____9-d
3

Answer 1

To find the area of the rectangle with dimensions 9-d by 3, multiply length by width to get the expression (9-d) × 3, then distribute the 3 to obtain the expanded expression 27 - 3d.

Step-by-step explanation:

The question is asking to write and expand an expression for the area of a rectangle. The formula for the area is the product of its length and width. Given the dimensions 9-d (length) and 3 (width), we would first write the expression for the area as:

Area = Length × Width

Area = (9-d) × 3

To expand this expression without brackets, we distribute the 3 across the terms inside the parenthesis:

Area = 3 × 9 - 3 × d

Area = 27 - 3d

This expanded expression represents the area of the rectangle in a form that no longer contains brackets.
