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=
× base × Height
Area of a right angle triangle=
× 4×6
Area of a right angle triangle=12 
Hence , the correct answer is 12 
Answer:
A
Step-by-step explanation:
If you would like to write <span>(-3 + √-9)^2 in a standard form a + i * b, you can do this using the following steps:
</span>(-3 + √-9)^2 = (-3)^2 - 2 * 3 * √-9 + (<span>√-9)^2 = 9 - 6 * 3 * i - 9 = 0 - 18 * i = -18 * i
</span>
The correct result would be -18 * i.
