For this case, the first thing you should do is find the area of the room. We can assume that the room is a rectangle, then the area will be:
A = (w) * (l)
Where,
w: width
l: long
Substituting the values we have:
A = (16) * (20)
A = 320 feet ^ 2
We note that each carpet covers only 4 feet ^ 2.
Therefore the number of carpets will be:
N = (320) / (4)
N = 80
Answer:
andy will need to buy 20 carpet squares to cover the room
An inconsistent system has no solution. The lines are exactly the same, so every coordinate pair on the line is a solution to both equations.
Answer: the perimeter of the shape is 19.1
Step-by-step explanation:
To determine the length of each side of the quadrilateral, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side
For line AD,
AD² = 2² + 4² = 4 + 16 = 20
AD = √20 = 4.47
For line AB,
AB² = 1² + 5² = 1 + 25 = 26
AB = √26 = 5.1
For line BC,
BC² = 2² + 4² = 4 + 16 = 20
BC = √20 = 4.47
For line CD,
CD² = 1² + 5² = 1 + 25 = 26
CD = √26 = 5.1
The perimeter of a plane figure is the distance around the figure. Therefore
Perimeter = AB + AB + BC + CD
Perimeter = 4.47 + 5.1 + 4.47 + 5.1 =
19.1
