If a rectangle's length is
2t+1
and the width is
t-3 write an expression for the perimeter and an expression for the area.

For this case we have that by definition:

The area of a rectangle is given by:

Where:

a and b are the sides of the rectangle.

For its part, the perimeter will be given by:

If we have as data:

So, the area is given by:

We apply distributive property:

For its part, the perimeter is:
