Question

In square ABCD, IF AB = (5x + 4) cm, BC = (7x - 10)cm. Find the value of x and length of AD. ​Jjj

Answer 1

Reffer to the above attachment.

X=7

AD=39

Answer 2

Answer:

AB = BC = CD = AD.....( ALL sides of square are equal)

5x + 4 = 7x - 10.

On transposing we get,

10 + 4 = 7x - 5x

14 = 2x

14/2 = x

x = 7

AD = 5x + 4

AD = 5( 7 ) + 4

AD = 35 + 4

AD = 39

Therefore, the value of x is 7 and the length of AD is 39 cm.
