Answer:

Perimeter

P = P1+P2

P1 = 4a           P2=2(a+b)

P1=4*5           P2=2(3+5)

P1=20            P2=2*8

                     P2=16

P = 20+16

P=36

Area

A=A1+A2

A1=[tex]a^{2}[/tex]                 A2=a*b

A1=[tex]5^{2}[/tex]                 A2=3*5

A1=25                A2=15

A=25+15

A=40
