Answer:
1 : 6
Step-by-step explanation:
Calculate the perimeter
perimeter = 2(3x + 5) + 2(6x + 10) = 6x + 10 + 12x + 20 = 18x + 30
perimeter = 18x + 30 ← take out a common factor of 6 from both terms
= 6(3x + 5)
ratio of width : perimeter
= 1(3x + 5) : 6(3x + 5) ← divide both parts by (x + 5)
= 1 : 6

![- 24 \div 4 = - 6](https://tex.z-dn.net/?f=%20-%2024%20%5Cdiv%204%20%3D%20%20-%206)
[tex] - 24 \div 4 = \\ \frac{ - 24}{4} \\ = \frac{ - 12}{2} \\ = /frac{-6}{1}
Answer:
![2(\frac{1}{2} *20*50)+2(\frac{1}{2} *20*10)](https://tex.z-dn.net/?f=2%28%5Cfrac%7B1%7D%7B2%7D%20%2A20%2A50%29%2B2%28%5Cfrac%7B1%7D%7B2%7D%20%2A20%2A10%29)
Step-by-step explanation:
The formula for the area of a triangle is ![\frac{1}{2} *b*h](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2Ab%2Ah)
The triangles that can be made is the triangle that has legs 20 and 50 and the triangle that has legs 20 and 10.
Since there are 2 of each triangles, we get:
![2(\frac{1}{2} *20*50)+2(\frac{1}{2} *20*10)](https://tex.z-dn.net/?f=2%28%5Cfrac%7B1%7D%7B2%7D%20%2A20%2A50%29%2B2%28%5Cfrac%7B1%7D%7B2%7D%20%2A20%2A10%29)
The answer that fits is the first option.
