a piece of tile is in the shape of a right triangle the base is 1 1/2 CM the height is 2 1/2 CM what is the area in square centimeters

To find the area of a triangle, you use the formula:

Area = 1/2 * base * height

In this case, the base is 1 1/2 cm and the height is 2 1/2 cm. We need to convert these fractions into a single fraction to calculate the area:

1 1/2 cm = 3/2 cm
2 1/2 cm = 5/2 cm

Now we can plug these values into the formula:

Area = 1/2 * 3/2 cm * 5/2 cm
Area = 1/2 * 3/2 * 5/2
Area = 15/4 square cm

Therefore, the area of the right triangle is 15/4 square centimeters or 3.75 square centimeters.
