Answer 1

Answer:

Area of rectangle is 1758.4 cm square.

Here, length of rectangular paper is given 14 cm.

Radius of cylinder is 20 cm.

So we have to find the breadth of rectangular paper.

Breadth= 2×pi×r

=2×3.14×20

=125.6 cm

Area of rectangle = length × breadth

= 14×125.6

=1758.4 cm square
