Question

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

Answer 1

Answer:

let,  

length of the rectangle = L

and, breadth of the rectangle = B

A.T.Q:-  

new length = L-5

new breadth = B- 5

and perimeter = 26

or, 2(L-5 + B-5) = 26  

=> 2(L+B -10) =26

=> L+B -10 =13

=> L+B =23
