Answer:
702 is the area of your first shape, 114 is the perimeter
20 is the area of your second shape, 24 for the perimeter
Step-by-step explanation:
You wanna break them down into smaller squares to find their area and perimeter.
18 * 24 = 432 (this is the area for the smaller rectangle)
9 * 30 = 270 (I got the 9 by subtrating the total length of your shape, which is 27, by that one part they gave which is 18)
270 + 432 = 702 is your area for your first shape
27 + 24 + 18 + 6 + 9 + 30 = 114 is the perimeter for your first shape
7 * 2 = 14 2 * 3 = 6 = 20 is the area for your second shape
2 + 3 + 3 + 2 + 3 + 2 + 2 + 7 = 24 is the perimeter of your second shape

Answer:
-60% decrease
Step-by-step explanation:
60 is the old value and 24 is the new value.
percent change = x 100%
so for this problem, you can substitute the values given in the formula:
percent change = x 100% = x 100% =
-60% (decrease)

Answer:
26.2655 miles
Step-by-step explanation:
Whenever possible, draw a diagram. I've attached a picture of the balloon and the lines of depression (not drawn to scale, of course).
As you can see, the angles of depression form alternate interior angles with the ground (angles of elevation). So these angles are also 13° and 39°.
We can use the tangents of these angles to find the base lengths of the two triangles that are formed.
tan 13° = 4 / a
a = 4 / tan 13°
tan 39° = 4 / b
b = 4 / tan 39°
So the total distance is:
a + b
= 4 / tan 13° + 4 / tan 39°
≈ 22.2655
