I don't think that there is enough info for this problem, but could someone try to help?

Answer:

Step-by-step explanation:

Rectangle : Let length = b & width = a

PQ = QR = 6

LR = QR - PL = 6 - a

ΔPQR ~ ΔMLR

In similar triangles, corresponding sides are in same ratio.

$\frac{PQ}{QR}=\frac{ML}{LR}\\\\\frac{6}{6}=\frac{a}{6-b}$

$1 =\frac{a}{6-b}$

6 - b = a

6 = a + b

a +b = 6

Perimeter of rectangle = 2*(length +width}

= 2*(a+ b)

= 2 * 6

= 12

If 3/x = 5/y , what is the value of y/x ?

VashaNatasha [74]

$\dfrac{3}{x} = \dfrac{5}{y}$

Cross-Multiply:
$3y = 5x$

Divide by 3 on both sides:
$y = \dfrac{5x}{3}$

Divide by x on both sides:
$\dfrac{y}{x} = \dfrac{5}{3}$
