Question

What is the area of the rectangle

4/5 cm top
9/10 cm side
?/? = square centimeters

Answer 1

To find the area of a rectangle, you multiply its length by its width. In this case, the dimensions given are:

- Length: \( \frac{4}{5} \) cm
- Width: \( \frac{9}{10} \) cm

Now, we can calculate the area:

\[
\text{Area} = \text{Length} \times \text{Width} = \frac{4}{5} \times \frac{9}{10}
\]

To multiply these fractions, we multiply the numerators and the denominators:

\[
\text{Area} = \frac{4 \times 9}{5 \times 10} = \frac{36}{50}
\]

Next, we simplify \( \frac{36}{50} \):

Both 36 and 50 can be divided by 2:

\[
\frac{36 \div 2}{50 \div 2} = \frac{18}{25}
\]

Therefore, the area of the rectangle is:

\[
\frac{18}{25} \text{ square centimeters}
\]
