Answer:
i. The length of the trap door is 12 feet, and its width is 7 feet.
ii. The perimeter of the trap door is 38 feet.
Step-by-step explanation:
The area of the trap door = 84 square feet. But the dimension of the grand piano = by .
For the piano to pass through the door conveniently, the width of the door should be wider than that of the piano. And its length the same. Given that the length and side measure of the door has to be a whole number, then;
The width of the door would be 7 feet, so that:
Area of the door = length × width
84 = l × 7
⇒ l = 12
The length of the trap door is 12 feet, and its width is 7 feet.
2. Since the traap door has a shape of a rectangle, thus:
perimeter of the trap door = 2 (length + width)
= 2 (12 + 7)
= 38 feet
The perimeter of the trap door is 38 feet.
