opposite sides of rectangle are congruent
x+y=30.....(1)
x-y=14......(2)
solving equation 1 and 2 we get
x=22 and after substituting the value of x in any of the equation we get value of y as 8
x+y=30.....(1)
x-y=14......(2)

opposite sides r congruent
therefore frm 1st condition
x+y =30
from 2nd condition
x-y=14
add equation 1 and 2
x+y=30
x-y=14
________
2x=44
x=11
sub. in equation 2
11-y=14
-y=14-11
-y=3
y=-3
therefore frm 1st condition
x+y =30
from 2nd condition
x-y=14
add equation 1 and 2
x+y=30
x-y=14
________
2x=44
x=11
sub. in equation 2
11-y=14
-y=14-11
-y=3
y=-3
