Let, the width of the rectangle is x meters 

So, the length of the rectangle is = (x+10) Meters

According to the question,

$$\begin{gathered} x\left(x+10\right)=1,200 \\ \Rightarrow x^2+10x-12,00=0 \\ \Rightarrow x^2+40x-30x-1,200=0 \\ \Rightarrow x\left(x+40\right)-30\left(x+40\right)=0 \\ \Rightarrow \left(x+40\right)\left(x-30\right)=0 \\ \Rightarrow x-30 \\ or, x=-40 (But the value of length cannot be a negative) \end{gathered}$$

So, the width of the rectangle is 30 meters, and

The length of the rectangle = 30+10=40 meters.

So, according to the Pythagorean theories.

The length of the diagonal of the rectangle= $\sqrt{{40}^2+{30}^2}=50$ meters. 

Let the length of the other diagonal= d meters

Area of rhombus =$\frac{1}{2}$$(10\times d)=5d$ 

According to the question, 

$$\begin{gathered} 5d-120 \\ d=24 \end{gathered}$$

So, the length of the other diagonal = 24 meters

Half of the one diagonal = $\frac{10}{2}=5$ meters and half of the other diagonal=$\frac{24}{2}=12$ 

One side of the rhombus  =$\sqrt{5^2+{12}^2}=\sqrt{169}=13$

So, the perimeter of the rhombus $4\times 13=52$  meters. ans.

Let, the length of a side of the triangle = a meters

We know, the area of an equilateral triangle= $\frac{\sqrt{3}}{4}{a}^2$

$$\begin{gathered} \frac{\sqrt{3}}{4}{a}^2=3\sqrt{3} \\ \Rightarrow a^2 = 12 \\ \Rightarrow a=\sqrt{12}=2\sqrt{3} \end{gathered}$$ meters.

The radius of the circle =$\frac{{\displaystyle \frac{1}{2}}}{\sqrt{3}}\times 2\sqrt{3}=1$ meter (the length of radius is $\frac{1}{2\sqrt{3}}$ times of a triangle side)

So, the required area $=\mathrm{\pi }\times 1^2=\mathrm{\pi }=\frac{22}{7}=3.1416$ square meters approximately. ans.

Eco-friendly Mobile Financial Services (MFS) can be ensured through branchless banking a mobile banking as mobile banking does not need any extra papers. It uses USSD, SIM Technological infrastructures to help people getting financial services. Here people enjo banking without banks.

Though Mobile Financial services is extraordinary by nature, it has some risks associated with it. Customers are often found they lose their electronic wallet. Electronic money is randomly transferred to other accounts. It can be mitigated by offering customers guarantee of 100% money back services.

Regulators often choose Bank Led MFS' over 'MNO Led MFS' Model because it is easy to provide services with banks than to MNO's lack of exposure in dealing with people's money. safeguarding people's money. Banks also get huge customers. They make them realize to open new accounts with them. So regulators always opt for Bank Led MFS.

An appropriate title for this comprehension can be "Mobile Financial Service Delivery model: MNO vs MFS"?
