let the breadth be x cm
so length = x+5 cm
perimeter of a rectangle = 2(l+b)
62 = 2(x+x+5)
62 = 2(2x+5)
4x+10 = 62
4x=52
x=52/4
x=13
 so the breadth is 13 cm and length is 13 + 5 = 18 cm
then the area is equal to 13 x 18
=234 cm ^{2}

hope it helps

breath= x cm      length= x+5cm                                                                                      perimeter of rectangle = 2 (l+b)                                                                                                   = 2  ( x+5+x )                                                                                                        62/2    = 2x + 5                                                                                                                31 - 5  = 2x                                                                                                                      26/2    = x                                                                                                                           x       = 13 cm                                                                                                                                                                                                                                                    area= l * b                                                                                                                               = 13 * 18                                                                                                                       = 234 cm2
