Answer 1

Hlo!! here's Ur Answer ⬇️⬇️

Take that total and divide the perimeter by it: 190 / 19 = 10. So each of those ratios need to be multiplied by 10. Final answers: 40 : 60 : 90. They have a ratio of 4:6:9 and add up to 190.

Answer 2

Step-by-step explanation:

let side be 2x 8x and 9x

perimeter = 76

2x+8x+9x = 76

19x = 76

x = 76/19

x = 4

side = 2x= 2× 4 = 8

8x = 8× 4 =32

9x = 9× 4 = 36
