<p>??????????</p>

2

<p>assume PS is one. that makes PT 2/5 and TS 3/5 </p>

<p>they gave you the area of RTS, which is 7</p>

<p>so (1/2)(3/5)(x)=7 solve for X and multiply it by PS (which is 1)</p>

3

<p>i need the area of the rectangle,not an x</p>

4

<p>um... that should give you the answer. especially since i just copied all my work from the question and i got the question right</p>

<p>you take what you get for X which is side RS and multiply it by 1 which is side PS.......... gives you 23.33333 which is 70/3 which is the answer.</p>
