4x + 7x + 2 + 7x + 8 = 154
18x = 154 - 10
18x = 144
x = 8

Sides: 32 m, 58 m , 64 m

The first to find the length of each side, we have to find the value of x :

(4x) + (7x + 2) + (7x+8) = 154


4x + 7x + 7x + 2+8 = 154


18x +10 = 154


18x = 154 - 10


18x = 144


x = (144)/(18)


\boxed{x=8}

Solution First side :

(4x)m = (4 \cdot 8)m = 32\ m

Solution Second Side :

(7x+2)m = (7(8)+2)m = 58\ m

Solution Third Side :

(7x+8)m = (7(8)+8)m = 64\ m
