if the base of a parallelogram is 2 1/2 and its height is 1 1/2 what is its area?

Area = base times height.

A = 2.5 * 1.5
A = ?

is the answer 3.75?

add 1 3/8+ 4 3/4+ 2 1/6

this is as far as i can go then i am lost.

11/8+19/4+13/6

Yes, 3.75 is correct for the area of the parallelogram.

For the sum of fractions, you have done the first step correctly.

The next step is to find the LCM of the three denominators. Confirm that it is 24. Now convert each fraction to an equivalent having 24 as denominator. Then add the numerators. The answer should be 199/24 or 8 7/24.

Yes. The answer is 3.75 square units.

add 1 3/8+ 4 3/4+ 2 1/6

First you need to find the common denominator and convert the fractions to their equivalents.

1 3/8 = 1 9/24
4 3/4 = 4 18/24
2 1/6 = 2 4/24

. . . . 6 31/24 = 7 7/24

I can't add.

Of course, DrBob is right. The answer is 8 7/24.

To find the area of a parallelogram, you multiply the length of the base by the height.

In this case, the base of the parallelogram is 2 1/2 and the height is 1 1/2.

To make the calculation easier, let's convert the mixed numbers to improper fractions.

The base can be written as 5/2 and the height as 3/2.

Now, multiply the base (5/2) by the height (3/2):

(5/2) * (3/2) = (15/4)

Therefore, the area of the parallelogram is 15/4 square units.
