Question

If the length of a line segment AB = 3 cm then 2AB will be
(a) 8 cm
(b) 6 cm
(c) 4 cm
(d) 9 cm

Answer 1

Given,

The length of line segment AB = 3 cm.

To Find,

The length of 2AB

Solution,

Since the length of line segment AB is given so the length of 2AB will be two times the length of AB or the length of AB added two times, which can be done as mentioned below.

2AB = AB+AB = 3+3 = 6cm.

Hence, the length of 2AB is 6 cm.

Answer 2

Answer:

Correct answer is option (b) 6 cm

Given problem:

If the length of a line segment AB = 3 cm then 2AB will be

(a) 8 cm   (b) 6 cm       (c) 4 cm        (d) 9 cm

Step-by-step explanation:

Given that length of the line segment AB = 3 cm

here we need to find the value of 2AB

given that length of AB = 3 cm

then the value of 2AB will  = 2×3 cm

                                            = 6 cm

correct answer is option (b) 6 cm
