choose the correct alternative. 1. when 5 is subtracted from length and breadth of the rectangle , the perim

2 thoughts on “choose the correct alternative. 1. when 5 is subtracted from length and breadth of the rectangle , the perim”

1. Step-by-step explanation:

   Let the length of rectangle be x

   Let breadth of rectangle be y

   When 5 is subtracted from length and breadth of rectangle,

   x → x-5

   y→ y-5

   Formula of perimeter of rectangle : 2(Length+Breadth)2(Length+Breadth)

   So, Perimeter = 2(x-5+y-5)2(x−5+y−5)

   26 = 2(x+y-10)26=2(x+y−10)

   \frac{26}{2} = 2(x+y-10)

   2

   26

   =2(x+y−10)

   13 = x+y-1013 = x+y−10

   23 = x+y23=x+y

   Hence the mathematical form of the statement is 23 = x+y23=x+y

   Let the length and breadth be x and y.

   According to the question, new length and breadth x-5 and y-5 respectively.

   Perimeter of rectangle = 26

   2(x – 5 + y – 5) = 26

   x + y – 10 = 13

   x + y = 23

   hope it helps…
