Let take the Example,

Given

Construct the quadrilateral PQRS in which PQ = 4 cm, QR = 3 cm, PS = 2.5 cm, PR = 4.5 cm and QS = 4 cm.

Step by Step

Step 1: Draw a line segment PQ = 4 cm.

Step 2: With 4.5 cm from P draw an arc.

Answer 2

We have

A + b = 5

by squaring both sides

(a+b)

+2ab=25

13+2ab=25

2ab=25−13

2ab=12

∴ ab = 6

Hence, the value of ab is 6.
