The living room of Mingming s house is 6 meters long and 4 meters wide, and I want to paste a 1 mete

Suppose you spread the trim strip to the ground:

Area = (6 + 4) * 2 * 1 = 20 (m).

The living room is 6 meters long and 4 meters wide, and the circumference is:

2*(6+4)=20 meters, this is the length of the decorative strip.

The area of the decorative strip: 20*1=20 square meters.

6*1*2+2*1*2=16 square meters.

Just look at the four rectangles and add them up.

(6+4)*2*1=20m^2

There are several doors and windows on all sides of the living room, or decoration in that area, the answer is uncertain.
