The perimeter of a square is directly proportional to the length of its sides.

A. Write an equation to represent this direct variation. Make sure to define your variables.

B. In complete sentences, use a specific example to justify your equation from part A. Include a drawing in your answer.

p=nL

Step-by-step explanation:

A. p = nL, where p is the 'perimeter', n is the number of sides, and L is the length of one side.  This equation holds true for any equilateral object.  

B. Since the sides of a square are all equal and there are four sides to a square, one can easily see that the perimeter is 4L... for example a 5 meter square would have a perimeter of 4x5, or 20 meters.

Or

Perimeter of a square is 4L with L being the length of one of its sides.

So P = 4L

If you use 8 as L, then P = 4 x 8 or 32.

So just draw a square and mark 8 and the length of one of its sides.

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
