Answer 1

area of frame-area of photograph=45*30-35*22=580cm raise to the power 2

Answer 2

Answer:

580 sq.cm.

Step-by-step explanation:

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

                         $=(45 \times 30)-(35 \times 22)$

                         $=580 cm^2$

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