visa cards begin with 4 and then have 13 or 16 digits but here we have a number beginning with 4 and then it has the 15 digits.

<u>Step-by-step explanation:</u>

Each card has a different first digit number. The maximum length of this type of credit card number can be up to 19 digits.

Scorpion4ik [409]

Answer:

The area of larger table is 24 square feet.

Step-by-step explanation:

Given are the length and width of small table

$l_s = 2\ ft\\w_s = 3\ ft$

The area of a rectangular table is calculated by multiplying the length and width. It is also given that the length and width of the larger table is double the length and width of small table

So the length and width of larger table will be:

$l_l = 2*2 = 4\ feet\\w_l = 3*2 = 6\ feet$

The area of larger table will be:

$A_l = l_l*w_l\\= 4 * 6\\=24\ ft^2$

Hence,

The area of larger table is 24 square feet.
