Answer:

120 $cm^{2}$

Step-by-step explanation:

Each fourth of the rhombus is equal, so when we find the area of 1 triangle, we can find the area of the entire shape.

The formula for the area of a triangle is 1/2(b*h).

In this case, b=5 and h=12.

5*12=60

60*(1/2)=30

Now that we've found 1/4, lets multiply by 4 to find the total.

30*4=120

Therefore, the answer is 120 $cm^{2}$

What is the solution to this equation 1/2n^2+18=0

ololo11 [35]

Answer:

n = ±6 .

Step-by-step explanation:

A quadratic equation is given to us and we need to find out the solution of the given equation . The given equation is ,

$\rm\implies -\dfrac{1}{2}n^2+18=0$

Subtracting 18 both sides ,

$\rm\implies -\dfrac{1}{2}n^2 = -18$

Multiplying both sides by -2 ,

$\rm\implies -2\times\dfrac{1}{2}n^2 = -2\times -18$

On simplyfing , we get ,

$\rm\implies n^2= 36$

Putting squareroot both sides ,

$\rm\implies n= \sqrt{36}$

This equals to ,

$\rm\implies \boxed{\quad\blue{\rm n =\pm 6 }}$

Hence the value of n is ±6 .
