Question

When 5 is subtracted from length and breadth of the rectangle the perimeter becomes 26.
What is the mathematical form of the statement ?
(a) x - y = 8 (b) x + y = 8 (C) x + y = 23 (d) 2x + y = 21​

Answer 1

Step-by-step explanation:

Answer:

23 = x+y23=x+y

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
