Question

word problem

Answer 1

If the length equals "m", and the width equals "4m", then the area of this carpet equals:

 

A = b * h

A = m * 4m

A = 4m² square meters

 

If the cost per square meter = $12, then the cost of the entire roll of carpet would be:

4m² * 12 = 48m²

 

The cost of the entire roll of carpet equals $48m²
