Area of path = Area of rectangle PQRS - Area of rectangle ABCD
= 68 x 33 – 65 x 30 = 2244 - 1950 = 240 sqm.
Let's discuss.
• Is there another way to find the area of the pathway in the problem above?
Example The length and the width of a mobile phone are 13 cm and 7 cm respectively.
It has a screen PQRS as shown in the figure.
What is the area of the screen?
Solution : ABCD is the rectangle formed by the edges of the mobile. PQRS is the rectangle
formed by leaving a 1.5 cm wide edge alongside AB, BC, and DC, and a 2 cm
