Also, I think that Brainly is an awesome app, but there's an app which is doing great work for me in maths, named Gauthmath. I will suggest it. Video concepts and answers from real tutors.

Ok I just have the phone number for my dad to go it
Answer:
95 cm^2
Step-by-step explanation:
perimeter(p)=39cm
L=3x-1
B=2x+3
Now,
p=2(l+b)
39=2(3x-1+2x+3)
39=6x-2+4x+6
39=10x+4
39-4=10x
x=35/10
x=3.5
Putting the value of x
L=3x-1; =3×3.5-1; =10.5-1; =9.5cm
B =2x+3; =2×3.5+3; =7+3; =10cm
Again,
A= L×B
=9.5×10
=95cm^2
