Answer 1

Answer:

Area of the poster is $1728$ square inches.

Step-by-step explanation:

First let's convert feet into inches.

1 feet = 12 inches

Length of the poster in inches:

$4$ feet = $4*12$ inches

                            =$48$ inches

Width of the poster in inches :

$3$ feet = $3*12$ inches

                            =$36$ inches

Area of a rectangle = Length * Width

Area of the poster = $48*36$

                                                =$1728$ square inches
