The coordinates of the vertices of LMN acquired a -ve sign to form the image L'M'N'. The line passes through the origin.
Step-by-step explanation:
When a point is rotated through 180° about the origin clockwise/anticlockwise, the coordinates of the object point T (h,k) takes a new position (-h,-k) to form the image T'. A line joining an object point to its image point will pass through the origin that is the center of rotation.

Let the width of the room be = x
Length of the room = 3x, Since it is three times as wide
Perimeter = 80m
Perimeter = 2*(L + W) = 2*(3x + x) = 80
2*(3x + x) = 80
2*(4x) = 80
8x = 80 Divide both sides by 8
x = 80/8
x = 10, But length = 3x, = 3*10 = 30
Length = 30m
Answer:
2(8y+9m)
Step-by-step explanation:
Answer:
52√3 ft ²
Step-by-step explanation:
Formula for area of the trapezoid:
a = Base = 11
b = Base = 15
h = Height = 4√3
Since the height is 4√3 we can turn it into a number:
4√3 = 6.92820323028 = 6.93
Now using the formula:
As you can see that it not a answer choice.
We can turn the answer choice into number:
44√3 ft ² = 76.21023553.. ≈ 76.20
44√3-24 ft ²=52.21023553.. ≈ 52.20
60√3 ft ² = 103.92304845.. ≈ 103.90
52√3 ft ² = 90.06664199.. ≈ 90.07
Thus, the answer is 52√3 ft ²
