1.	When 5 is subtracted from length and breath of the rectangle, the perimeter becomes 26. what is the mathematical form of the statement? *x-y=8x+y=8x+y=232x+y=21
Answer» (C) x + y = 23 Let the length of the rectangle be ‘x’ and that of breadth be ‘y’. PERIMETER of rectangle = 2[(x – 5) + (y – 5)] ∴ 26 = 2(x + y – 10) ∴ x + y – 10 = 13 ∴ x + y = 23

Answer»

Let the length of the rectangle be ‘x’ and that of breadth be ‘y’.

PERIMETER of rectangle = 2[(x – 5) + (y – 5)]

∴ 26 = 2(x + y – 10)

∴ x + y – 10 = 13

∴ x + y = 23
