Answer 2

Answer:

a) $2CD = 4.6$  and b) $3 AB = 13.5$

Step-by-step explanation:

Given : AB=4.5 cm CD =2.3 cm

To Find :constructs the following line segments a)  2CD b) 3AB

Solution:

AB = 4.5

$3 AB = 3 \times 4.5$

$3 AB = 13.5$

CD =2.3 cm

$2CD = 2 \times 2.3$

$2CD = 4.6$

So, a) $2CD = 4.6$  and b) $3 AB = 13.5$
