Answer 2

Calculating the Number of Square Frames

To calculate the number of square frames Oleg can make from a wire of length 250 cm, we can use the formula:

Number of frames = Total length of wire / Perimeter of each square frame

The perimeter of a square frame is calculated as 4 times the length of one side.

Calculation

Given: - Length of wire = 250 cm - Side length of square frame = 20 cm

Using the formula: Number of frames = 250 / (4 * 20)

Result

Number of frames = 250 / 80 = 3.125

Oleg will be able to make 3 square frames from the wire, with some wire left over.
