Calculate the area of the rectangle given its length and breadth.

(1) 5.2 cm, 2.5 cm


(2) 2.1 m, 1.5 m


(3) 3.5 m, 1.2 m

(1) Given :


Length(l) = 5.2 cm


Breadth(b) = 2.5 cm


Area of rectangle = (l × b)


⇒ Area of rectangle = 13 sq. cm


(2) Given :


Length(l) = 2.1 m


Breadth(b) = 1.5 m


Area of rectangle = (l × b)


⇒ Area of rectangle = 3.15 sq. m


(3) Given :


Length(l) = 3.5 m


Breadth(b) = 1.2 m


Area of rectangle = (l × b)


⇒ Area of rectangle = 4.2 sq. m
