Area of a right triangle with length of 1 1/2 and width of 2 1/2

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

Area = 1/2 * base * height

In this case, the base (length) is 1 1/2 and the height (width) is 2 1/2.

Convert the mixed numbers to improper fractions:
1 1/2 = 3/2
2 1/2 = 5/2

Now plug these values into the formula:

Area = 1/2 * 3/2 * 5/2
Area = 1/2 * 3/2 * 5/2
Area = 1/2 * 15/4
Area = 15/8

The area of the right triangle with a length of 1 1/2 and width of 2 1/2 is 15/8 or 1 7/8 square units.
