Answer:
42 units
Step-by-step explanation:
Lengths:
(-2,6)(6,6)
6 - -2 = 8
(1,-6)(-7,-6)
1 - - 7 = 8
(6,6)(1,-6)
sqrt[(-6-6)² + (1-6)²]
sqrt(169) = 13.
(-2,6)(-7,-6)
sqrt[(-6-6)² + (-7--2)²]
sqrt(169) = 13
Perimeter = 8 + 8 + 13 + 13

Dixon is 6 feet tall, Ariadne is 4 feet tall by proportion.
What in mathematics is a proportion?
- A proportion is an equation that sets two ratios at the same value.
- For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4)
We can use the proportion.
We already know that Dixon is 6 ft tall and that his shadow is 9 ft long.
Also we know that the shadow of his sister is 6 ft long.
6 : x = 9 : 6, or 6 / x = 9 / 6.
After that we will cross multiply : 9 * x = 6 * 6,
9 x = 36 ,
x = 36 /9,
x = 4.
Ariadne is 4 feet tall.

The complete question is -
Dixon and his little sister Ariadne stand next to each other on the playground on a sunny afternoon. Their mother measures their shadows. Dixon's shadow is 9 feet long and Ariadne's shadow is 6 feet long. If Dixon is 6 feet tall, how tall is Ariadne?
The student should compute 6*180 = 1080 because of the formula
S = 180(n-2)
We have n = 8 sides which leads the n-2 part to become n-2 = 8-2 = 6
