Question

The ratio of the measures of the sides of a polygon is 1:3:5:6 and the perimeter is 270. What is the length of the second smallest side?

Answer 1

Answer:

54

Step-by-step explanation:

let the sides be x, 3x, 5x, and 6x

x+3x+5x+6x= 270

15x =270

x = 18

length of second smallest side = 54

Answer 2

Answer:

54

Step-by-step explanation:

first, you add the ratios

1+3+5+6= 15

the second smallest side is the one with 3

so this means that the second ratio will be used

place 3 over the total which is 15

then multiply the total perimeter by the fraction 3/15

(3/15)x270=54

the lenght of the second side is 54
