Length L of photograph = 14 2/5
= (14 x 5 + 2) / 5
= 72/5 cm
Breadth B of photograph = 10 2/5
= (10 x 5 + 2) / 5
= 52/5 cm
Border b = 2 3/5
= (2 x 5 + 3) / 5
= 13/5 cm
So area of framed photograph = (L + 2b).(B + 2b)
2b = 13/5 x 2 = 26/5
Area = (72/5 + 26/5).(52/5 + 26/5)
Area = 98/5 x 78/5
Area = 7644/25 cm^2
Or we can write
Area = 305 19/25 cm^2
= (14 x 5 + 2) / 5
= 72/5 cm
Breadth B of photograph = 10 2/5
= (10 x 5 + 2) / 5
= 52/5 cm
Border b = 2 3/5
= (2 x 5 + 3) / 5
= 13/5 cm
So area of framed photograph = (L + 2b).(B + 2b)
2b = 13/5 x 2 = 26/5
Area = (72/5 + 26/5).(52/5 + 26/5)
Area = 98/5 x 78/5
Area = 7644/25 cm^2
Or we can write
Area = 305 19/25 cm^2
