Start with a right angled triangle. Adjacent side = 12, opposite side = 1 is given to you.
 
1.5 meters given to you is opposite side. Adjacent side you can calculate. Since the slope must be same
 1/12 = 1.5/x
 
x = 12 times 1.5 = 18
 
That means stairs of the house must be the diagonal of a right angled triangle whose adjacent side is 18m and opposite side = 1.5m
 
Diagonal 2 = 182 + 1.52
 
Diagonal = length of stairs = √(182+1.52) = 18.06m
