The area of rectangle is 21.
Step-by-step explanation:
Area of rectangle = length[tex]\times[/tex]breadth
length are same ⇒ 2b+1 = 3b-2
⇒ 3b-2b = 1+2
⇒ b =3
⇒ length = 3
breadth are same ⇒ 4a+3 = 5a-4
⇒ 5a-4a = 3+4
⇒ a = 7
⇒ breadth = 7
⇒ Area of rectangle = 3[tex]\times[/tex]7
⇒ Area of rectangle = 21
