Makovka662 [10]

Answer:

12 $centimeters^{2}$

Step-by-step explanation:

Length of first leg of a Right angle triangle= 4 centimeters

Length of second leg of a Right angle triangle= 6 centimeters

We have to find the area of tiles

Area of tiles= Area of Right angle triangle

Area of a right angle triangle= $\frac{1}{2}$ × base × Height

Area of a right angle triangle= $\frac{1}{2}$ × 4×6

Area of a right angle triangle=12 $centimeters^{2}$

Hence , the correct answer is 12 $centimeters^{2}$
