The perimeter of a rectangle is 100 cm and its length is 30 cm . what is the breadth of the rectangle ? what is the area of the rectangle?

Answer»

Perimeter of rectangle = 2(length + BREADTH)
----------------------------------

100= 2(30+ breadth)

100/2 = 30+ breadth

50=30 + breadth

50-30= breadth

20cm = breadth


-----------------------------------

Then,

Area of rectangle =length×breadth

Area of rectangle = 30×20

Area of rectangle = 600 cm²


I hope this will help you
