pls answer it very IMP​

Answer 1

Here is your answer..........

Answer 2

Answer:

opposite sides of rectangle are equal.

so,

2x-y-18=x-2y+9. 2x+6=3y

x+y-27=0......(1). 2x-3y+6=0.......(2)

BY ELIMINATION METHOD;

multiply eq.(1) by 2 and subtract it from (2)

2x-3y+6=0

2x+2y-54=0

-. -. +

-------------------

-5y+60=0

so, y=12

and x=15

Now,

Perimeter=2(l+b). {l=27;b=36)

=2(27+36)

=2×63

=126

area = lb

=27×36

= 972
