Answer 2

Answer:

Step-by-step explanation:

perimeter = 2(l + b)

half perimeter =  l+b = 36                   ............eq 1

now,

           l = b+ 4

putting this value of l in eq1,

           b +4 + b = 36

                2b     = 32

                   b     =  16

putting b = 16 in eq 1

                       l +  16 = 36

                             l   =   36-16

                              l   =    20
