Answer:
Area of rug for half room = 4.25a feet²
Explanation:
Given:
One side of rectangular room = 8.5 feet
Find:
Area of rug for half room
Computation:
Assume;
Another side of rectangular room = a feet
So,
Area of rectangle = length x width
Area of rectangle room = 8.5 x a
Area of rectangle room = 8.5a feet²
Area of rug for half room = Area of rectangle room / 2
Area of rug for half room = 8.5a / 2
Area of rug for half room = 4.25a feet²
