Answer:
Perimeter of Δ ABC = 7 + 8 + 9 = 24 cm
Step-by-step explanation:
In  triangle Δ XYZ , 
A is the mid point of XY
B is the midpoint of YZ
 C is the mid point of XZ
 AY = 7 
BZ =8
XZ = 18
The mid - point theorem states that,
The segment formed by connecting two mid - points of a triangle is parallel to the third side and half as long
AY = 7 then BC = 7 cm
BZ = 8 then AC = 8 cm
XY = 18 then AB = 9 cm
Perimeter of Δ ABC = 7 + 8 + 9 = 24 cm
 
        
             
        
        
        
$270 equals 135% of the original price
270/x=135/100
135*2=270
100*2=200
Final answer: $200
