Find the area of of the rectangle: length 5 ft and width 13 ft

i do not understand what it is asking me!

To find the area you multiply the length(5) by the width(13).
5×13=65
The area of the rectangle is 65.

The formula for area is:
A=l times W
A= 5 times 13
A=65
So the area of the rectangle is 65 square ft

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
