The perimeter of triangle ABC is 24 units
Step-by-step explanation:
If a segment joining the mid points of two sides of a triangle, then 
this segment is:
- Parallel to the third side
- Its length is half the length of the third side
In The triangle XYZ
∵ A is the mid point of XY
∵ B is the mid point of YZ
∴ AB =  XZ
 XZ
∵ XZ = 18 units
- Substitute the value of XZ in AB
∴ AB =  × 18 = 9 units
 × 18 = 9 units
∵ B is the mid point of YZ
∵ C is the mid point of XZ
∴ BC =  XY
 XY
∵ AY = 7 units
∵ AY =  XY
 XY
∴ XY = 2 × AY
∴ XY = 2 × 7
∴ XY = 14 units
∴ BC =  × 14 = 7 units
 × 14 = 7 units
∵ A is the mid point of XY
∵ C is the mid point of XZ
∴ AC =  YZ
 YZ
∵ BZ = 8 units
∵ BZ =  YZ
 YZ
∴ YZ = 2 × BZ
∴ YZ = 2 × 8
∴ YZ = 16 units
∴ AC =  × 16 = 8 units
 × 16 = 8 units
∵ The perimeter of a triangle = the sum of the lengths of its sides
∴ Perimeter Δ ABC = AB + BC + AC
∴ Perimeter Δ ABC = 9 + 7 + 8 = 24 units
The perimeter of triangle ABC is 24 units

T=number of  tiles bought
cost at store 1 is 0.79t+24
cost at store 2 is 1.19t
when will be equal cost?
0.79t+24=1.19t
minus 0.79t from both sides
24=0.4t
divide both sides by 0.4
60=t
answer is 60 tiles
