Five-year math application problem in primary school, this painting is twice as long as it is wide. I used 1.8 meters of wood to make the picture frame. What are the length, width and area of this painting? The length of this painting is twice as wide. I used 1.8 meters of wood as the frame. What is the length, width and area of this painting?

2+ 1=3 copies 1.8 divided by 2 = 0.9m

0.9 x 2/3 = 0.6

0.9x3 1 = 0.3m

0.6x0.3 = 0. 18m2

A: The length, width and area of this painting are 0. 18 square meters respectively.
