Given: The length and breadth of a rectangle are in the ratio 5 : 3. the length is 8 m more than the breadth. Formula used: area of rectangle = length × breadth Calculation: The ratio of length and breadth of rectangle = 5 : 3 ⇒ length of rectangle = 5x, breadth of rectangle = 3x ⇒5x−3x=8 ⇒2x=8 ∴x=4 length of rectangle =5x=5×4=20m breadth of rectangle =3x=3×4=12m area of rectangle = length × breadth ⇒20×12=240m2
