Question

when 5 is subtracted from length and breadth of rectangle the perimeter become 26 what ls the mathematical form of the statement???​

Answer 1

Step-by-step explanation:

Let length and breadth of a rectangle be x and y.

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

Perimeter of rectangle = 26

2(x - 5 + y - 5) = 26

x + y - 10 = 13

x + y = 23

Answer 2

2 ( l - 5 + b - 5 ) = 26

=> l + b - 10 = 13

=> l + b = 23
