Ans:
Ratio of length and width of rectangle must be in proportion to the actual length and width of the rectangle.
Let we consider width of rectangle be = x
Ratio of Length : Width is = 5 : 2 respectively
Actual Length is = 40 cm
Now we know that, they are in proportion, so we can write them as,
5 : 2 = 40 : x
∴ 5/2 = 40/x
Cross multiplying, we get
5x = 80
x = 16 cm
Therefore width of rectangle is 16 cm.
Hello friends my name is Rajakumar Dayashankar Gupta . Here I am started to write blog on name scientechplus . I am started to writing this blog post on science , technology and engineering since 2020 . I completing my ssc , than after I go for stream in science field , than after completing my 12th science than later I realize my self , I am interested in electronics fields , so I start learning in diploma electronics engineering . My journey is quite interesting to choosing right decision of my aim . And I want to explain the concept in simple and precise way . I every time want to learn something new , it means that something new from open minded from our environment . To learn something new from our expectation . It quite special and very interested to hear that , when we imagine or think we go to learn something very uniqueness our eyes fill with glow , that moment is such a very great pleasurable moment we feel isn't it ? . And I want to share the information , facts , knowledge related to all science , technology and engineering in detail , simple and precise way .
