To find the new height, we need to multiply the current height by the ratio of increase.

The ratio of increase is 2:3, which means that for every 2 units of increase in the first quantity, there are 3 units of increase in the second quantity.

Therefore, to find the new height, we can set up the following proportion:

2/3 = x/140

Cross-multiplying, we get:

2 * 140 = 3 * x

280 = 3x

Dividing both sides by 3, we get:

x = 280/3

x ≈ 93.33

Therefore, the new height is approximately 93.33 cm.
