Question

The perimeter of a rectangle is 36. Its breadth and length are in the ratio 3:5. What is its breadth and length

Answer 1

Answer:

perimeter of rectangle = 2 (l+ b)

36= 2(3x+5x)

36=6x+10x

36= 16x

36/16=x

9/4= x

Answer 2

Step-by-step explanation:

Given , the perimeter of rectangle is 36

and Let the sides be 3x and 5x resp.

now , the perimeter of rect. = 36

2(l+b) =36

2(3x + 5x) = 36

6x + 10x = 36

16x = 36

x = 36/16

x = 9/4

breadth = 3x = 3×9/4 = 27/4

lenght = 5x = 5 × 9/4 = 45/4
