Answer 1

Given: Anmol's chart paper size = 90 cm$\times$ 40 cm
Here, let 90 cm = length and 40 cm = breadth

$\therefore$ Area of rectangle = Length$\times$Breadth
⇒ 90 cm $\times$ 40 cm = 3600 sq cm

Similarly, Abhishek's chart paper size = 50 cm$\times$70 cm
Here, let 50 cm = length and 70 cm = breadth

$\therefore$ Area of rectangle = Length$\times$Breadth
⇒ 50 cm $\times$ 70 cm = 3500 sq cm

Difference in area = 3600 sq cm - 3500 sq cm = 100 sq cm
Hence, Anmol's chart paper will cover more area on the table.
