Because the triangles are similar, their corresponding sides will have the same ratio. Side corresponding to PQ is AC and side corresponding to RC is PR. Thus:
RC/PR = AC/PQ
5.1 / 3.4 = 4.2 / PQ
PQ = 2.8 inches

Find the value of t in the diagram

12345 [234]

In a trapezoid, with bases $b$ and $B$ and height $h$ , the area is given by

$A = \frac{(B+b)h}{2}$

In your case:

$B = BC = 3t$

$b = AD = t$

$h = AB = t$

so, the formula becomes

$A = \frac{(3t+t)t}{2} = \frac{4t^2}{2} = 2t^2$

Since the area is $50 \text{cm}^2$ , we have

$2t^2 = 50 \iff t^2 = 25 \iff t = 5$
