Answer: 50 feet, 150 feet, 75 feet, and 180 feet
Step-by-step explanation:
The side lengths are x, 3x, 1.5x and 180 (in feet) and they must all add up to 455 feet, so ....
x + 3x + 1.5x + 180 = 455
(1+3+1.5)x + 180 = 455
5.5x + 180 = 455
Subtract 180 from both sides
5.5x = 275
x = 275/5.5
x = 50 feet , but that was not really the question.
The question was the 4 side lengths.
The lengths are x, 3x, 1.5x and 180, all in feet.
x = 50 feet ----> 50 feet
3x = 3(50 feet) ---> 150 feet
1.5x = 1.5(50 feet) ---> 75 feet
180 feet (given)
We check our work by adding the four sides ---> 50+150+75+180 = 455, so that looks good.
Don't forget to label the lengths in feet!
I hope this helps.
