Answer 1

8*4=32 см отрезали
100-32=68 см осталось

Answer 2

Problem Analysis

We are given a wire of length 100 cm, from which a piece is cut to make a square frame with a side length of 8 cm. We need to determine how many centimeters of wire are left.

Solution

To find the length of the wire remaining, we need to subtract the perimeter of the square frame from the original length of the wire.

The perimeter of a square is given by the formula: perimeter = 4 * side length.

Given that the side length of the square frame is 8 cm, we can calculate the perimeter as follows:

perimeter = 4 * 8 = 32 cm.

To find the length of the wire remaining, we subtract the perimeter of the square frame from the original length of the wire:

length of wire remaining = original length of wire - perimeter of square frame.

Substituting the values, we have:

length of wire remaining = 100 cm - 32 cm = 68 cm.

Therefore, there are 68 centimeters of wire remaining.

Answer

The length of wire remaining is 68 centimeters.
