Answer:
The side length of the square is 3 meters.
The side length of the triangle is 4 meters.
Step-by-step explanation:
This is basically a systems of equations word problem.
To solve this, we have to create two different equations. Let's assume 
is the side length of the square and 
is the side length of the triangle.
We can make the equation 
, since the perimeters are the same. (A square has 4 sides, a triangle has 3 - multiplying by the side length of each will get perimeter)
We also know that the side length of the triangle is 1 meter longer than the side length of the square, so the equation here becomes 
.
Now, let's substitute the second equation () into the first ().
Apply the distributive property:
Subtract 3s from both sides:
So the side length of the square is 3. We can now plug it into the equation 
to find the side length of the triangle.

A turtle walks 7/8 mile in 50 minutes.
Convert 1 hour to minutes and you get 60 minutes.
50/60 = 5/6. The turtle walks 7/8 mile in 5/6 hour
The turtle walks 21/20 or 1.05 miles per hour.
1/10 = .1
__ x .1 = .0 49
__ = .49
.049 divided by .1 = .49

Let <em>A</em> be your age, <em>B</em> be the age of your brother and <em>S</em> be the age of your sister.
Since your brother is 1/4 your age, then:
Since your sister is 8 years older than your brother, then:
Since your sister is 12 years old, then:
Use the second equation to find your brother's age by plugging in <em>S=12</em>:
Plug in <em>B=4</em> in the first equation to find your age:
Therefore, you are 16 years old.
