Length is greater by 20%
20/100*15
20/20*3
=3cm
Then length of tray is =(3+x) cm
Width is 15cm
Length=15+3=18cm
20/100*15
20/20*3

Then length of tray is =(3+x) cm
Width is 15cm

length = X
width= 15cm
so length = 15+20% of 15
= 15+20÷100×15
= 15+3
= 18 cm
width= 15cm
so length = 15+20% of 15
= 15+20÷100×15
= 15+3
= 18 cm
