Since an <em>octagon</em> has 8 equal sides, multiply the given 35ft length by 8 to get total perimeter.

$35 * 8 = 280 ft$

Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age

Lostsunrise [7]

Answer: The answer is x = 65 - 60y.

Step-by-step explanation: Given that Miguel is the grandfather of Raul and Paula is Raul's sister.

Now, let 'x' years be the age of Raul and 'y' years be the age of Raul's sister (Paula).

Also, given is the following information -

Raul's age = Grandfather's age - 60 × sister's age.

Since the age of Miguel, Raul's grandfather is 65 years, so we can write the following equation to find Paula's age

$x=65-60\times y\\\\\Rightarrow 60y=65-x\\\\\Rightarrow y=\dfrac{65-x}{60}.$

Thus, we can find Paula's age (y) using the equation

$y=\dfrac{65-x}{60},$

where 'x' is the age of Raul.

Crank

Answer:

perimeter = 56 m

area= 196 m^2

Step-by-step explanation:

perimeter = 4 x sides = 4 x 35(2/5) = 4 x 14 = 56 m

area= sides^2 = (35 x $\frac{2}{5} )^{2}$ = 14^2 = 196 m^2
