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.
Both the equations are the same so there is no point of intersection then the equation has no solution.
The system of equations that has no solution is, the correct option is A.

Which system of equations has no solution?
<h3>What is a system of equations?</h3>
A system of linear equations is a collection of two or more linear equations.
The set of equations "which cannot be solved for x and y values is said to have no solution".
The system of equations has no solution is;
Divided by 5 equation 1
Divided by 2 equation 2
Hence, both the equation are the same so there is no point of intersection then the equation has no solution.
