A piece of a tile is in the shape of a right triangle the base is 1 1/2 cm and a height is 2 1/2 cm what is the area in square centimeters
4 cm
3 3/4 cm
1 7/8 cm
8 cm
The area of a triangle is given by the formula:
Area = (1/2) * base * height
Given that the base is 1 1/2 cm and the height is 2 1/2 cm, we can substitute these values into the formula:
Area = (1/2) * (3/2) * (5/2)
= (3/4) * (5/2)
= 15/8 cm^2
Therefore, the area of the right triangle is 15/8 cm^2, which can also be written as 1 7/8 cm^2. Thus, the correct answer is 1 7/8 cm^2.
