The dimension of picture are 30*20cm.what length of wooden frame is needed to frame the fence it, what is the length of the wire needed?
The perimeter of a rectangle is twice the length plus twice the width
To find the length of the wooden frame needed to frame the picture, we need to calculate the perimeter of the picture. The perimeter is the sum of all the sides.
Since the picture has dimensions 30 cm by 20 cm, the perimeter can be calculated as follows:
Perimeter = 2 * Length + 2 * Width
Substituting the given values:
Perimeter = 2 * 30 cm + 2 * 20 cm
Perimeter = 60 cm + 40 cm
Perimeter = 100 cm
Therefore, the length of the wooden frame needed to frame the picture is 100 cm.
Now, let's calculate the length of wire needed to fence it. Assuming you want to enclose the picture with a wire lattice, you would need wire along the perimeter of the wooden frame.
Using the previously calculated perimeter of 100 cm, that would be the length of wire required to fence the picture.
