Question

The perimeter of
rectangle is 48cm and it's breadth and length are in the ratio 3:5
what is the breadth and length ?​

Answer 1

Answer:

(18,30)

Step-by-step explanation:

lets the length be 3x

width be 5x

perimeter = 48

so

3x +5x=48

8x = 48

x =48/8

x= 6

so.

3x = 3×6 = 18

5x = 5×6= 30

Answer 2

Answer:

9cm& 15cm

Step-by-step explanation:

LET THERE ARE x IN RATIOS.

LENGTH OF RECTANGLE = 5x

BREADTH OF RECTANGLE = 3x

GIVEN:- PERIMETER = 48 cm

PERIMETER=2(length + breadth)

=> 48 = 2( 5x + 3x )

=> 48/2 = 8x

=> x = 24/8

x = 3

BREADTH = 3×3=9 cm & LENGTH = 5×3=15 cm.
