Answer:

Part 1) [tex]PR=9\ units[/tex]

Part 2) [tex]PQ=12\ units[/tex]

Part 3) [tex]PS=15\ units[/tex]

part 4) [tex]QR=15\ units[/tex]

Part 5) [tex]RT=7.5\ units[/tex]

Step-by-step explanation:

we know that

In a rectangle opposite sides are parallel and congruent

The measure of each interior angle is 90 degrees

The diagonals are congruent and bisect each other

step 1

Find the length of side PR

we know that

[tex]PR=QS[/tex] ----> by opposite sides

we have

[tex]QS=9\ units[/tex]

therefore

[tex]PR=9\ units[/tex]

step 2

Find the length of side PQ

we know that

[tex]PQ=RS[/tex] ----> by opposite sides

we have

[tex]RS=12\ units[/tex]

therefore

[tex]PQ=12\ units[/tex]

step 3

Find the length of diagonal PS

we know that

[tex]PS=2PT[/tex]---> the diagonals bisect each other

we have

[tex]PT=7.5\ units[/tex] ---> given problem

therefore

[tex]PS=2(7.5)=15\ units[/tex]

step 4

Find the length of diagonal QR

we know that

[tex]QR=PS[/tex]---> the diagonals are congruent

we have

[tex]PS=15\ units[/tex]

therefore

[tex]QR=15\ units[/tex]

step 5

Find the length of RT

we know that

[tex]QR=2RT[/tex]---> the diagonals bisect each other

we have

[tex]QR=15\ units[/tex]

substitute

[tex]15=2RT\\RT=7.5\ units[/tex]
