To find the area of the dilated rectangle, we first need to determine the new dimensions after dilation using the scale factor of 2.5.
The original dimensions of the rectangle are:
- Length = 10 inches
- Width = 4 inches
After dilation:
- New Length = 10 inches × 2.5 = 25 inches
- New Width = 4 inches × 2.5 = 10 inches
Now, we can calculate the area of the dilated rectangle:
\[
\text{Area} = \text{Length} \times \text{Width} = 25 \, \text{inches} \times 10 \, \text{inches} = 250 \, \text{square inches}
\]
Thus, the area of the dilated rectangle is **250 square inches**.
The original dimensions of the rectangle are:
- Length = 10 inches
- Width = 4 inches
After dilation:
- New Length = 10 inches × 2.5 = 25 inches
- New Width = 4 inches × 2.5 = 10 inches
Now, we can calculate the area of the dilated rectangle:
\[
\text{Area} = \text{Length} \times \text{Width} = 25 \, \text{inches} \times 10 \, \text{inches} = 250 \, \text{square inches}
\]
Thus, the area of the dilated rectangle is **250 square inches**.
