Find an example of a 2 dimensional object in your house that is rectangular or triangular.
1 answer:
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
