Answer 2

Hey dear!!

__________________________________________________________________

Dimensions of the photograph = 25 cm × 12 cm

Length of frame needed to frame the picture = perimeter of the picture 

= 2(l+b)

= 2(15+10)

= 2 × 25

= 50 cm

Therefore, length of frame needed to frame the picture is 74cm.
