Answer:

Perimeter = 10 cm

Area = 6.25 cm²

Step-by-step explanation:

\bf \: Given :

\sf \: Side  \:  of \:  the \:  square = 2.5 \: cm

\bf \: To \:  find:

\rightarrow \sf \: Perimeter

\sf\rightarrow Area

\bf \: Solution :

\rm \: First \:  w e \:  need \:  to \:  find  \: out  \: the  \: perimeter \:  o f \:  it.

So to find the Perimeter of the square, we'll use this formula :

\boxed{  \sf\longrightarrow \: Perimeter = 4 \times side}

\bf \: Step  \: 1 : \rm \:  Put \:  the  \: value  \: of   \: side \:  of \:  the  \: square :

\sf\longrightarrow \: Perimeter = (4 \times 2.5)cm

\bf \: Step\;2 : \rm Multiply :

\sf\longrightarrow \: Perimeter  = 10 \: cm

Hence, the perimeter would be 10 cm .

\rule{225pt}{2pt}

\sf \: Now,\; let's\; find  \: the  \: Area .

We know that the formula of Area to find the square is,

\boxed{ \sf \longrightarrow \: Area = (side) {}^{2} }

Note : The answer would always be in cm².

\bf Step\;  1  :\rm Put\;  the\; value \; of\;  side \; of \; the\; square :

\sf\longrightarrow{Area} = (2.5) {}^{2}  \: cm {}^{2}

\sf\longrightarrow{Area} = (2.5 × 2.5 ) \: cm {}^{2}

\bf \: Step\;2 : \rm Multiply :

\longrightarrow\sf \: Area = 6.25 \: cm {}^{2}

Hence, the area of the square would be 6.25 cm².

<em>We are done !</em>

\rule{225pt}{2pt}

I hope this helps!

Let me know if you have any questions.

Solve for x. The triangles are similar.
Serjik [45]

Answer:

\fbox {D. 10}

Step-by-step explanation:

As the triangles are similar :

45/55 = (12x - 3)/143

9/11 = (12x - 3)/143

9 x 13 = 12x - 3

12x = 117 + 3

12x = 120

x = 10
