200 cm by 150 cm
=============
To find the actual measurements of Jane's bed, we need to multiply the measurements on the scale drawing by the scale factor.
The scale factor in this case is 50.
So, to find the length of her bed, we multiply 4 cm by 50, which equals 200 cm.
Similarly, to find the width of her bed, we multiply 3 cm by 50, which equals 150 cm.
Therefore, the actual measurements of Jane's bed are 200 cm by 150 cm.
