QUESTION :

In square ABCD. AD = 8b-9: AB = 9-b, Find CD

ANSWER :

We know that all sides of a square are equal,

so, AB = BC = CD = DA

So, AD = AB

8b-9 = 9-b

8b+b = 9+9

9b = 18

b = 2

Therefore, CD = AD = AB

CD = 8b - 9

CD = 8(2) - 9

CD = 16 - 9

CD = 7cm

Therefore, all sides of the given square = 7cm

AB = BC = CD = DA = 7cm

FINAL ANSWER : 7cm
