Step-by-step explanation:

Given-

Breadth = 12cm

Perimeter = 46cm

Solution -

so, Perimeter of a rectangle = 2 [ l+b ]sq.units

= 2[l + 12]cm = 46 cm

= l + 12 = 46/2

            = 23cm

= l = 23 - 12

    = 11cm

So, the length is 11cm.

Check-

Perimeter of a rectangle = 2[ l + b ]sq.units

                                           = 2 [ 11 + 12 ]cm

                                           = 2*23

                                           = 46cm
