Answer:
let the breadth be x then length = (2x - 5)
according to the question
x+2 = b
( 2 x - 5)-5 = l
perimeter = 74
therefore
perimeter of rectangle = 2 ( l+b )
74 = 2 ( 2x - 5 - 5 + x + 2 )
74 / 2 = 3x - 8
37 + 8 = 3x
45 = 3x
45/3 = x
15 = x
if x = 15 then
l = 2x - 5
2×15 - 5
30 - 5
= 25
b= x
= 15
