Answer 1

Step-by-step explanation:

=> let AB = 4x & BC = 3x

=> using Pythagoras

=> AC = √( (4x)² + (3x)² )

=> AC = 5x

=> breadth of rectangle = 4/5*(5x) =4x

=> perimeter of rectangle

=> 2(4x+5x) = 180

=> 9x = 90

=> x = 10

=> then smallest side

=> 3x

=> 3*10

=> 30 cm.

Answer 2

Answer:

x= 10

Then the smallest sude = 3×10= 30
