Answer:
120 km squared.
Step-by-step explanation:
The shape shown has 5 sides: three rectangles and 2 triangles.
If you examine each triangle closely, they are 3-4-5 triangles. The area of one triangle is 3 * 4 * 1/2 = 12 * 1/2 = 12 / 2 = 6. Since there are two triangles, the total area of the triangles is 6 * 2 = 12 km squared.
The three rectangles have the same length, but their widths differ. They all have a side length of 9 km, but the largest rectangle has a width of 5 km, the medium has a width of 4 km, and the smallest has a width of 3 km.
So, the rectangles' areas added up will be (9 * 5) + (9 * 4) + (9 * 3) = 45 + 36 + 27 = 108 km squared.
And so, the total surface area is 12 km squared + 108 km squared, or 120 km squared.

Answer:
<h2>
y - 1 = -3(x - 5)</h2>
Step-by-step explanation:
An equation in point-slope form of the line that passes through the point (<em>x₁,y₁</em>) and has a slope of <em>m</em>:
y - y₁ = m(x - x₁)
m = -3
(5, 1) ⇒ x₁ = 5, y₁ = 1
Therefore:
y - 1 = -3(x - 5)

Answer:
Length of rotated segment = 94 cm
Step-by-step explanation:
Rotation is transformation of a figure or a segment about a center which rotates the figure or segment about the center with the angle of rotation.
Rotation is that type of transformation in which the image and pre-image are congruent. This means that rotation has no effect on shape and size of figure or segment and thus, the shape and size of the figure or segment remains same after rotation.
It is given that a segment of length 94 cm is rotated 
degrees around a center 
.
The rotation will have no effect on size of the segment as stated above.
Thus, the segment after rotation will still measure 94 cm.
