Question

nthng much  jst answer it because i have to prepare for exams

Answer 1

The area to be covered is 25×18=450m².

The length of 60cm carpet required to cover this area is 450/0.60=750m.

Since the 18m width can be covered exactly by 18/0.6=30 widths of the carpet, and there are no restrictions on the length. 25 strips of the carpet, each measuring 25×0.6=15m², would be required:

30×15=450m².
