Question

photograph is of length 5/2cm and breadth 7/2 cm respectively.
if it has a border around it of uniform width 1 cm, then find the area of the framed photograph
​

Answer 1

Answer:

16 cm^2

Step-by-step explanation:

area of the photograph = lb = (5/2 * 7/2)cm^2 = 35/4 cm^2

area of the photograph including frame = lb = {(5/2 + 2)(7/2 + 2)}cm^2 = {9/2 * 11/2}cm^2 = 99/4 cm^2

area of the frame = area of the photograph including frame - area of the photograph = 99/4 cm^2 - 35/4 cm^2 =  64/4 cm^2 = 16 cm^2
