Answer:

$2p=348 cm\: S=6726 cm^{2}$

Step-by-step explanation:

Ciao, come stai?

1) Per prima cosa, dobbiamo trovare la misura della base più grande. Scomponendo la figura possiamo visualizzare un triangolo e un quadrato. Ci sono somiglianze con gli angoli. Quindi è un triangolo rettangolo. Applichiamo il teorema di Pitagora:

$a^2=b^2+c^2\\95^2=b^2+76^2\\57=b$

2) Perimetro:

$2p=60+57+76+60+95\\2p=348 cm$

3) L' area

$\frac{(B+b)h}{2} =\frac{(117+60)76}{2} =6726 \:cm^{2}$

Remember the formula y = mx+b.

'm' in mx is the slope.

'b' is the y-intercept.

So in the equation y = -3x - 3...

The slope is -3. The y-intercept is -3.

I hope you find this answer the most helpful! :)
