To solve the problem in the image, we are tasked with finding both the area and perimeter of a rectangular poster with dimensions 0.73 meters by 1.1 meters.

Step-by-step Solution:

1. Area (A) of a rectangle:

The formula for the area $A$ of a rectangle is: $A = \text{length} \times \text{width}$ Given:

• Length = 1.1 meters
• Width = 0.73 meters

Thus: $A = 1.1 \, \text{m} \times 0.73 \, \text{m} = 0.803 \, \text{m}^2$

2. Perimeter (P) of a rectangle:

The formula for the perimeter $P$ of a rectangle is: $P = 2 \times (\text{length} + \text{width})$ Given:

• Length = 1.1 meters
• Width = 0.73 meters

Thus: $P = 2 \times (1.1 \, \text{m} + 0.73 \, \text{m}) = 2 \times 1.83 \, \text{m} = 3.66 \, \text{m}$

Final Results:

• The area $A$ is $0.803 \, \text{m}^2$.
• The perimeter $P$ is $3.66 \, \text{m}$.

Answer choices:

• The correct answer for the area is option e. 0.803 m².
• The correct answer for the perimeter is option c. 3.66 m.
