7/4 means you have to do 7 divided 4. You would get 1.75 then you have to do 1.75 times -4. You get -7. -7 is the answer.

Step-by-step explanation:

Given:

Length of box = 16 inches.

Width of the box = 12 inches.

We need to find find the area of the tissue paper.

But It is given that the area of the tissue paper sheet is based on twice the length times the width of the box.

Hence Framing in equation form we get;

Area of tissue paper = $2(length\ of \ box \times width \ of \ box)$

Hence Substituting the given values we get;

Area of tissue paper = $2(12\times 16) = 2\times 192 = 384 in^2$

Hence Area of tissue paper is 384 square inches.
