Question

A rectangle has a length of ( + ) and a width of ( − ). Determine the expression that represents the area of this rectangle.

Answer 1

Explanation:

The expression that represents the area of a rectangle with length (l) and width (w) is given by:

A = l * w

Therefore, the expression that represents the area of a rectangle with a length of ( + ) and a width of ( − ) can be represented as:

A = ( + ) * ( − ) = + × − = + (−) = −.
