Answer 1

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.
