Answer:
44.73 mph
Step-by-step explanation:
Answer:
1. P = 14cm; A = 10cm^2
2. P = 24cm; A = 12cm^2
3. P = 32cm; A = 63cm^2
4. P = 36cm; A = 80cm^2
5. P = 32cm; A = 60cm^2
6. P = 36cm; A = 81cm^2
7. P = 26cm: A = 30cm^2
8. P = 28cm; A = 49cm^2
9. P = 26cm: A = 42cm^2
Step-by-step explanation:
Formula to find perimeter for a rectangle:
length + width + length + width
l + w + l + w
Formula to find area for a rectangle:
length × width
l × w
1.
Perimeter (P): 5 + 2 + 5 + 2 = 14
Area (A): 5 × 2 = 10
2.
P: 6 + 2 + 6 + 2 = 24
A: 6 × 2 = 12
3.
P: 7 + 9 + 7 + 9 = 32
A: 7 × 9 = 63
4.
P: 10 + 8 + 10 + 8 = 36
A: 10 × 8 = 80
5.
P: 10 + 6 + 10 + 6 = 32
A: 10 × 6 = 60
6.
P: 9 + 9 + 9 + 9 = 36
A: 9 × 9 = 81
7.
P: 10 + 3 + 10 + 3 = 26
A: 10 × 3 = 30
8.
P: 7 + 7 + 7 + 7 = 28
A: 7 × 7 = 49
9.
P: 6 + 7 + 6 + 7 = 26
A: 6 × 7 = 42
Area will always have its units squared (cm^2) because the formula requires we multiply the numbers and therefore the units: cm × cm = cm^2

The y-values are increasing, as x increases in this problem.
Answer:
Building's actual height 32 meters
Building's shadow height 20 meters
Person's shadow height 1.2 meters
Person's actual height = ?
Find the person's actual height:
This is a proportion problem.
Actual height to shadow height
Building = Person
32 : 20 = x : 1.2
32 * 1.2 = 20 * x
38.4 = 20x
38.4/20 = 20x/20
1.92 = x
The person's actual height is 1.92 meters long.
32 : 20 = 1.92 : 1.2
32/20 = 1.60
1.92/1.2 = 1.60
