Question

Draw a line segment PQ of length 7 cm. Mark a point R on it such that l(PR) : l(RQ) = 4:1

Answer 1

Answer:

Locate a point R on PQ such that point is 5.6 cm away from P

Step-by-step explanation:

Step 1 : Draw a line segment PQ = Length 7cm using Ruler

PR : RQ = 4 : 1

=> PR/RQ = 4/1

=> PR  = 4RQ

PQ = PR + QR

=> PQ = 4RQ + RQ

=> PQ = 5RQ

=> RQ = PQ/5

=> RQ = 7/5

=> RQ = 1.4 cm

PR = 4 * 1.4 = 5.6 cm

Locate a point R on PQ such that point is 5.6 cm away from P
