Find an example of a 2 dimensional object in your house that is rectangular or triangular.
Dmitry_Shevchenko [17]

Answer:

A = 216 cm^2

P = 80 cm

Step-by-step explanation:

l = 12

w = 18

As the object is rectangular, the area is height * width and the perimeter is

2(height + width) as there are two of each side.

12 * 18 = 216 U^2   U = unit of measurement, I would presume for a poster you use cm so its 216 cm^2

12 + 18 = 40

40 * 2 = 80 cm
