Answer 2

Step-by-step explanation:

Perimeter of rectangle = 2(l+b)

= 2(l+b) 243=2(9+b)

= 2(l+b) 243=2(9+b) 243-18=2b

= 2(l+b) 243=2(9+b) 243-18=2b 255/2=b

= 2(l+b) 243=2(9+b) 243-18=2b 255/2=b 122.5 = b

= 2(l+b) 243=2(9+b) 243-18=2b 255/2=b 122.5 = bArea of rectangle =l×b

= 2(l+b) 243=2(9+b) 243-18=2b 255/2=b 122.5 = bArea of rectangle =l×b243 =9xb

= 2(l+b) 243=2(9+b) 243-18=2b 255/2=b 122.5 = bArea of rectangle =l×b243 =9xb243/9=b

= 2(l+b) 243=2(9+b) 243-18=2b 255/2=b 122.5 = bArea of rectangle =l×b243 =9xb243/9=b27=b
