Answer: 2,955 feet squared.
Step-by-step explanation: The area is the width times the height. The area of the whole room is 64*48=3,072 and when excluding the area of the carpet which is 9*13=117 you get 3,072-117=2,955 feet squared.
Answer:
The equation of the line is y = 6x - 2 .
Step-by-step explanation:
Formula for the equation of line is.
Where m is the slope.
As given
If (-6,-38) and (5,28) are two anchor points on the trend line.
Than
m = 6
Put the value in the equation of a line.
y = 6x +36 - 38
y = 6x - 2
Therefore the equation of the line is y = 6x - 2 .
Answer:
18cm
Step-by-step explanation:
We have the length of the rectangle but we need to find the width which we'll call w. Area is a, l is length.
a = l * w
20 = 5 * w
divide both sides by 5 to cancel the multiplication by 5 on the right side
4 = w
The rectangle is going to have two sides that are the length of l, and two sides that are the the length of w. We're looking for the perimiter p.
p = 2l + 2w
p = (2 * 5) + (2 * 4)
p = 18
As you can see there are two triangles but it can be done calculating just for one. First we must understand how formula for area of triangle works.
Where 
represents base (hypotenuse) and 
as height of the triangle.
We know that:
Using this data we fill the formula.
Hope this helps.
