Answer :
Using point q as the centre of dilatation and a scale factor of 2, line segment lm is dilated to form l'm'. The length of segment qm' is twice the length of segment lm.
1. The length of lm is the original length of the line segment.
2. The center of dilation is point q.
3. The scale factor is 2.
4. Therefore, the length of qm' is twice the length of lm.
The length of qm' is twice as long as the length of lm, meaning that qm' is twice the length of lm. The center of dilation is point q, and the scale factor used is 2, so qm' is twice the length of lm.
