Answer:

Answer: 580 sq.cm.

Explanation:

As per the question we have the following data with us:

Length of photo = 35 cm

Width of photo = 22 cm

Length of frame = 45 cm

Width of frame = 30 cm

Now to find the area of border

Area of border = Outer area - Inner area                          

(45*30) – (35*22)

= 1350-770

=580                    

Hence the area of the border is 580 sq.cm."
