Question

of all four side of rectangle is 41cm and its length and breadth are in ratio of 2 is to 5.find the length and breadth of the rectangle

Answer 1

Answer:

The perimeter of a rectangle is P = 90 cm

Let length of rectangle l is 5x

and breadth of rectangle b is 4x

Formula of perimeter of a rectangle is = 2( l + b )

So, 2( 5x + 4x ) = 90

2( 9x ) = 90

9x = 90/2

9x = 45

x = 45/9 = 5

Now length is 5x = 5*5 = 25 cm

and breadth is 4x = 4*5 = 20 cm

Now area of rectangle is = l x b

= 25 * 20 = 500 cm2

Hence length is 25 cm, breadth is 20 cm and area is 500 cm2
