Question

take a line segment pq of length 10cm. from pq cut off line segment pa of length 4.3cm and line segment bq of length 2.5cm. measure the length of line segment ab

Answer 1

Answer:

Step-by-step explanation:

Given,

PQ=10 cm

BQ=2.5cm

PA=4.3cm

PQ-(PA+AQ)=(10-6.8)cm

=3.2cm

Answer 2

the length of line segment ab = 3.2 cm

Step-by-step explanation:

Step 1 : Draw a line segment PQ = 10 cm

Step 2 : Using compass width = 4.3 cm Taking P as  center draw an arc intersecting PQ at A

Step 3 : Using compass width = 2.5 cm Taking Q as  center draw an arc intersecting PQ at B

Step 4 : Measure AB using ruler

AB   = 3.2 cm

PQ = PA + AB + BQ

=> 10 = 4.3 + AB + 2.5

=> 10 = 6.8 + AB

=> AB = 10 - 6.8

=> AB = 3.2 cm

the length of line segment ab = 3.2 cm
