To find the width of the doodad, we need to subtract the length of the one side from the total perimeter.
Let's denote the width of the doodad as "w".
The perimeter of a rectangle can be calculated by adding the lengths of all four sides together.
Given that the total perimeter of the doodad is 40 inches, and the length of one side is 12 inches, we can set up the following equation:
Perimeter = 2*(Length + Width)
40 inches = 2*(12 inches + w)
Now, let's solve for "w":
40 inches = 24 inches + 2w
Subtracting 24 inches from both sides:
16 inches = 2w
Dividing both sides by 2:
8 inches = w
So, the width of the doodad is 8 inches.
To find the area of the doodad, we multiply its length by its width.
The length of the doodad given is 12 inches, and the width we just found is 8 inches.
Area = Length * Width
Area = 12 inches * 8 inches
Area = 96 square inches
Therefore, the area of the doodad is 96 square inches.
