Answer:

26.36, 52.72, 65.90

Step-by-step explanation:

write the formula

2x + 4x + 5x = 145

add all the xs together

11x = 145

find x

11x ÷ 11 = 145 ÷ 11

x = 13.1818

subsitute the value of x to 2x, 4x, and 5x to find the side lengths

2(13.1818) = 2.3636

4(13.1818) = 52.7272

5(13.1818) = 65.909
