Answer:
12 square feet
Step-by-step explanation:
You can find out how many square feet he bought by dividing 432 by 3.
432/3=144
Now, you need to find the square root of that to find the length of just one side of the room.

Answer:
5/6 = 20/24
5/8 = 15/24
Step-by-step explanation:
These are the answers because:
1) First, the least common denominator is 24 because 8 x 3 is 24 and 6 x 4 is 24
2) Next, multiply the numerators with the same number you multiplied with the denominator
5 x 3 = 15
5 x 4 = 20
3) Therefore, the answers are:
5/6 = 20/24
5/8 = 15/24
Hope this helps!
Answer: 5 feet
Step-by-step explanation: A rectangle is a quadrilateral with 4 sides. The opposite sides are parallel and have the same length.
Top and bottom of the window are opposite, so they have the same measure of 3 feet.
One length of the window is 5 feet. Since the last side is opposite to the length of the window, it has the same length, i.e., its value is 5 feet.
