Answer:
A = 24182 ft²
Step-by-step explanation:
The dimension of the poster she has to decorate is 113 feet by 214 feet. It is in the shape of a rectangle. She can find the area by using the formula for the area of a rectangle.
A = lb
Here, l = 113 feet and b = 214 feet
A = 113 ft × 214 ft
A = 24182 ft²
Hence, the total area of the poster is 24182 ft².
