Question

5. A, B, C, D are the four points on a line segment, such that AB = 2 cm, CD = 40
AD = 10 cm. The length of BD is
(b) 7 cm
(c) 6 cm
(d) 5 cm
(a) 8 cm ​

Answer 1

Answer:

(a) 8 cm

By the above conditions

CD is the longest segment in which

Point A is 10 cm away from D

so that AB is 2cm

By these ,

AD= 10cm, AB= 2 cm and BD =?

AD-AB=BD

so that 10-2 = 8cm

Step-by-step explanation:

Answer 2

Answer:

The length of BD is 8 cm

Step-by-step explanation:

• The largest segment is CD=40 cm. Thus points A, B lies between C and D.

• The length of the line AD=10cm. This is the line segment that contains point B between them.
• The length of the line segment AB is 2 cm.
• The line segment AD can be represented by

        $AB+BD=AD\\BD=AD-BD\\BD=10-2\\BD=8 cm$

• The length of BD is 8 cm
