Answer:

12.8ft²

Step-by-step explanation:

Assuming that the poster is rectangular we can find the area of the poster using the formula for area of a rectangle

Area of a rectangle = length times width

Given side lengths: 3.2 and 4.

Area = 3.2 * 4 = 12.8

Answer

12.8

Step-by-step explanation:

The key to the explanation  is:

H=height

L=length

A=area

I first did 3.2x4 which is  12.8, I got that by doing 3x4 which is 12, then do .2x4 which is .8, I then added them together to get 12.8.

The formula that you would use in the future is HxL=A.

So for the answer it is 12.8 feet.

Hope you now understand the question!
