Find the perimeter of a square with side a. Are the perimeter of the square and the length of its side directly proportional qua

erik [133]

Answer:

The perimeter is 8 cm.

Yes, the perimeter of a square is directly proportional to its side length.

Step-by-step explanation:

Given:

The side length of the square is, $a=2\ cm$

The perimeter of a square is the sum of all of its side lengths. The perimeter of a square of side length 'a' is given as:

$P=a+a+a+a=4a$

Plug in $a=2\ cm$ and find perimeter, 'P'. This gives,

$P=4\times 2=8\ cm$

Therefore, the perimeter is 8 cm.

Now, two quantities are directly proportional only if their ratio is a constant.

Let us find the ratio of 'P' and 'a'.

We have, $P=4a$

Dividing both sides by 'a', we get:

$\frac{P}{a}=\frac{4a}{a}\\\frac{P}{a}=4(Constant)$

Therefore, the ratio of perimeter and side length is a constant. Hence, these are directly proportional quantities.

It is the formula to find the longest line on a right triangle. for example, a squared plus b squared equals c squared. In this case, c must always be the line not relating to the right angel.

The diagonals of a rhombus are 12 in. and 16 in. long. The length of a side of the rhombus is 10 in. What is the height of the r

iris [78.8K]

If d₁ and d₂ are the lengths of the diagonals, the area is given by
.. A = (1/2)*d₁*d₂
.. A = (1/2)*(12 in)*(16 in)
.. A = 96 in²

If b is the base and h is the height, the area is given by
.. A = b*h
We know the values of A and b, so
.. 96 in² = (10 in)*h
.. (96 in²)/(10 in) = h = 9.6 in

The height is 9.6 in.

What is the solution to the system of linear equations?

Natalija [7]

Answer:

The solution to a system of linear equations is the point at which the lines representing the linear equations intersect. Two lines in the x y xy xy -plane can intersect once, never intersect, or completely overlap.
