Answer:

He is correct because the key term is "greater than". This indicates that inequalities should be used here. Now, we write the inequality.

Explanation:

Let L = length

Let w = width

Perimeter = 2L + 2w

L = 100

Perimeter > 400

2(100) + 2w > 400

200 + 2w > 400 is the inequality

Subtract 200 on both sides of inequality.

2w > 200

w > 100

The width is at least 100 centimeters.
