4 324 ft.2

33/8 ft.2

4 1/8 ft.2

Answer 1

To find the area of the poster, you need to multiply the length and width.

The length of the poster can be written as 2 1/4 ft, which is equivalent to 9/4 ft.

The width of the poster can be written as 1 5/6 ft, which is equivalent to 11/6 ft.

Multiplying these fractions gives:

(9/4 ft) * (11/6 ft) = 99/24 ft^2

To write the answer as a mixed number in simplest form, you need to simplify the fraction.

99/24 = (8 * 12 + 3) / 24 = 99/24 = 4 3/24 = 4 1/8 ft^2.

Therefore, the area of the poster is 4 1/8 ft^2.
