The question asks for the area of a rectangular poster in square meters, given its dimensions in centimeters.

Here's how to solve it:

Given:

• Length = 15 cm
• Width = 12 cm

Steps:

1. Convert dimensions to meters: Since there are 100 centimeters in 1 meter:

   • Length in meters = $\frac{15}{100} = 0.15$ meters
   • Width in meters = $\frac{12}{100} = 0.12$ meters

2. Calculate the area: The area $A$ of a rectangle is given by: $A = \text{Length} \times \text{Width}$ Substituting the values: $A = 0.15 \times 0.12 = 0.018 \text{ square meters}$

Thus, the area of the poster is 0.018 square meters.
