The length and width of a rectangle can be expressed as (3x + 1) and (2x-7). Write and expression to represent the perimeter and an expression to represent the area.

Area:

The expression for area would be length x width, therefore the expression would be (3x + 1) (2x - 7)

Perimeter:

There are many expressions for perimeter. Here are some of them:

Length + width + length + width

2length + 2width

2 (length + width)

Let's use the first one, for example. The expression would be (3x + 1) + (2x - 7) + (3x + 1) + (2x - 7).
