Answer:

176 units

Step-by-step explanation:

All sides of this octagon are of the same length. Thus, x + 7 = (4/3)x - 1/3.

Mult. all terms by 3 will remove the fractions: 3x + 21 = 4x - 1.

Then 22 = x. The perimeter of this figure is 8(22), or 176 units.

Answer:

Solution,

∆ ACB = ∆ EFD

finding the value of X,

$\frac{x}{3.8} = \frac{15}{5}$

Apply cross product property

$x \times 5 = 15 \times 3.8$

Calculate the product

$5x = 57$

Divide both sides by 5

$\frac{5x}{5} = \frac{57}{5}$

Calculate

$x = 11.4$
