Answer:
5 feet²
Step-by-step explanation:
The area of entrance = area of triangle
Height, h = 2 1/2 feets
Width, w = 4 feets
The Area of a triangle is given as :
1/2 * base * height
Base = width = 4 feets
Area of entrance = 0.5 * 4 * 2.5
Area of entrance = 5 feet²
Hence, the area of the entrance is 5 feet square.
