Answer 1

[AI-generated answer — Bot GPT 3.5]

To calculate the length of tape needed to cover the edges of the photo frame, we first need to find the perimeter of the frame.

The perimeter of a rectangle can be calculated using the formula:
Perimeter = 2(length + width)

Given that the frame measures 30cm by 20cm, the perimeter can be calculated as:
Perimeter = 2(30 + 20)
Perimeter = 2(50)
Perimeter = 100cm

Therefore, the length of tape needed to cover the edges of the photo frame would be 100cm.
