when the painting is enlarged to a height of 15.3 cm, it will be approximately 32.52 cm wide.
To find out how wide the painting will be when enlarged to a height of 15.3 cm while maintaining the same aspect ratio, you can use the following proportion:
(Original width) / (Original height) = (New width) / (New height)
Plug in the values:
(3.6 cm) / (1.7 cm) = (New width) / (15.3 cm)
Now, solve for the new width:
New width = (3.6 cm / 1.7 cm) * 15.3 cm
New width ≈ 32.52 cm
