a )let the sides be 5x,4x,5x and 4x
given that 5x+4x+5x+4x=90
=> 18x=90
=>x=90/18
=>x=5
therefore the sides are 25 cm,20 cm,25 cm,20 cm
b) let the angles be x,2x,3x and 4x
as we know that angles of a quadrilateral is equal to 360 degree
so
=>x+2x+3x+4x=360
=>10x=360
=>x=36
therefore, the angels are 36 ,72, 108 , 146
