Question

A square painting painting is surrounded by a frame. the outside edges of the frame are 3 inches in length, and the frame is 3 inches thick. What is the total area of the frame?

Answer 1

Area = 36
`inches ^ 2`

Explanation:

There must be an error with the statement, because it is strange that the length of the frame is equal to its thickness.

Assuming that the data supplied is correct, we can do the following procedure.

Let's call L the length of the frame.

We know how much each side of the square measures.

L = 3 inches

We also know that the thickness (s) is:

s = 3 inches.

Then the area of ​​the frame is equal to:

Area = Perimeter * thickness

Area = 4L*s

Area = 3*4*3

Area = 36
`inches ^ 2`
