Question

Which figure has a greater area
12 cm by18.2 cm
13.5 cm x 15 cm

Answer 1

To find which figure has a greater area, we will calculate the area of each rectangle using the formula:

\[
\text{Area} = \text{length} \times \text{width}
\]

1. For the first rectangle (12 cm by 18.2 cm):
\[
\text{Area}_1 = 12 \, \text{cm} \times 18.2 \, \text{cm} = 218.4 \, \text{cm}^2
\]

2. For the second rectangle (13.5 cm by 15 cm):
\[
\text{Area}_2 = 13.5 \, \text{cm} \times 15 \, \text{cm} = 202.5 \, \text{cm}^2
\]

Now, we compare the areas:

- Area of the first rectangle: \( 218.4 \, \text{cm}^2 \)
- Area of the second rectangle: \( 202.5 \, \text{cm}^2 \)

Since \( 218.4 \, \text{cm}^2 > 202.5 \, \text{cm}^2 \), the figure with dimensions 12 cm by 18.2 cm has a greater area.
