Question

a rectangular pster has a length of 72 centimeters, and a width of 15 centimeters, the poster was reduced in size by 6 centimeters in length, and 3 centimeters in width, whats the area of the new poster

Answer 1

To find the area of the new poster after it has been reduced in size, we first need to determine the new dimensions.

1. **Original Dimensions:**
- Length = 72 cm
- Width = 15 cm

2. **Reduction in Size:**
- New Length = Original Length - Reduction in Length
\[
\text{New Length} = 72 \text{ cm} - 6 \text{ cm} = 66 \text{ cm}
\]
- New Width = Original Width - Reduction in Width
\[
\text{New Width} = 15 \text{ cm} - 3 \text{ cm} = 12 \text{ cm}
\]

3. **Area of the New Poster:**
\[
\text{Area} = \text{New Length} \times \text{New Width}
\]
\[
\text{Area} = 66 \text{ cm} \times 12 \text{ cm} = 792 \text{ cm}^2
\]

The area of the new poster is \(792 \, \text{cm}^2\).
