To solve the problem of finding the areas of the given parallelograms, we will use the formula for the area of a parallelogram:
\[
\text{Area} = \text{base} \times \text{height}
\]
Step-by-Step Solution:
####
a)
-
Base = 6 cm
-
Height = 4 cm
\[
\text{Area} = 6 \, \text{cm} \times 4 \, \text{cm} = 24 \, \text{cm}^2
\]
####
b)
-
Base = 9 km
-
Height = 5 km
\[
\text{Area} = 9 \, \text{km} \times 5 \, \text{km} = 45 \, \text{km}^2
\]
####
c)
-
Base = 6 mm
-
Height = 7 mm
\[
\text{Area} = 6 \, \text{mm} \times 7 \, \text{mm} = 42 \, \text{mm}^2
\]
####
d)
-
Base = 12 cm
-
Height = 4 cm
\[
\text{Area} = 12 \, \text{cm} \times 4 \, \text{cm} = 48 \, \text{cm}^2
\]
####
e)
-
Base = 10 m
-
Height = 3 m
\[
\text{Area} = 10 \, \text{m} \times 3 \, \text{m} = 30 \, \text{m}^2
\]
####
f)
-
Base = 12 cm
-
Height = 4 cm
\[
\text{Area} = 12 \, \text{cm} \times 4 \, \text{cm} = 48 \, \text{cm}^2
\]
Final Answers:
\[
\boxed{
\begin{array}{ll}
\text{a)} & 24 \, \text{cm}^2 \\
\text{b)} & 45 \, \text{km}^2 \\
\text{c)} & 42 \, \text{mm}^2 \\
\text{d)} & 48 \, \text{cm}^2 \\
\text{e)} & 30 \, \text{m}^2 \\
\text{f)} & 48 \, \text{cm}^2 \\
\end{array}
}
\]
