Answer 2

11 square centimeters of red paper will be visible on top.

Explanation:

Width of the rectangular red sheet = w = 4 cm

Length of the rectangular red sheet = l = 2 × 4 cm = 8 cm

Area of the rectangle = l × w

Area of the rectangular red sheet = A

`A=8 cm* 4 cm = 32 cm^2`

Width of the rectangular blue sheet = w' = 3 cm

Length of the rectangular blue sheet = l' = 7 cm

Area of the rectangular blue sheet = A'

`A'=7 cm* 3 cm = 21 cm^2`

After gluing blue paper on the top of red paper. The area of red paper that will be visible from the top is:

A - A' =
`32 cm^2-21 cm^2=11 cm^2`
