If the length of Mike’s rectangular poster is 2 times its width. If the perimeter is 12 inches, what is the area of the poster?

seraphim [82]

Answer:

Area of Poster = 23 sq inches

Step-by-step explanation:

Let say Width of Rectangular Poster = W inches

then Length of Rectangular Post = 2W inches

Perimeter = 2 ( W + 2W) = 6W inches

Perimeter given = 12 inches

Equating both

6W = 24

=> W = 4

Width of Poster = W = 4 Inches

Length of Poster = 2W = 2 * 4 = 8 inches

Area of Poster = 4 * 8 = 32 sq inches
