Ali wishes to make a frame for his class picture. The picture measures 50 cm by 24 1/2 cm. How many centimeters of molding will he need?

We just need to get the perimeter since the frame surrounds it:
[tex]Perimeter=2(l+w)=2(50+24.5)cm=2(74.5)cm=149cm[/tex]

Normally, frames are rectangle or square, since it has different length, it is a rectangular frame:

P=2(l+w)
Substitute with the given measurements
P=2(50 cm+24.5 cm)
P=2(74.5 cm)
P=149 cm

Hope this helps =)
