Question

Dilate the segment with a scale factor of r=1/2

Answer 1

3.5 cm long

Explanation:

AB*1/2=7*1/2=3.5

Answer 2

|AB'| = 3.5 cm

Explanation:

Given:

• |AB| = 7 cm
• r = ¹/₂

To dilate the line segment by a scale factor r, multiply the original length of the line segment by the given scale factor:

`\begin{aligned}\implies \sf |AB'|&=\sf |AB| * r\\\\&=7 * (1)/(2)\\\\&=(7 * 1)/(2)\\\\&=(7)/(2)\\\\&=3.5\; \sf cm\end{aligned}`
