A science fair poster is a rectangle 4 feet long and 3 feet wide. What is the area of the poster in square inches?

a_sh-v [17]

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
