Anmol has a chart paper of measure 90cm × 40cm, whereas Abhishek has one which measures 50cm × 70cm. Which will cover more area on the table and by how much?

Given:

For first chart paper:

Area of first chart paper = 90 × 40

= 3600 sq.cm

For second chart paper:

Area of second chart paper = 50 × 70

= 3500 sq.cm

Hence first chart paper will cover more area by 100 sq.cm.
