Question

if perimeter of rectangle is 2304 cm and length and breadth are in ratio of 5 x and 3 X find its length and breadth​

Answer 1

Step-by-step explanation:

Given perimeter = 2304cm

length = 5x

breadth = 3x

2 ( l + b ) = 2304

2 ( 5x + 3x ) = 2304

2 ( 8x ) = 2304

16x = 2304

x = 2304/16

x = 144

hence... length = 5x = 5 × 144 = 720cm

and breadth = 3x = 3 × 144 = 432cm

Answer 2

Answer:

total perimeter=2304 cm

                        =5x + 3x + 5x + 3x

                        =16x

x=2304÷16

=144

length=144x5

          =720 cm

breadth=144x3

            =432 cm
