22.
In rectangle PQRS, PR = 18x – 25, and QS = x + 825. Find the value of x and the length of each diagonal.

x = 50; PR = 875; QS = 875
x = 51; PR = 893; QS = 893
x = 50; PR = 437.5; QS = 437.5
x = 25; PR = 850; QS = 850

Answer 12

same principle, different names.
PR=QS

Answer 13

so would it be x = 50; PR = 437.5; QS = 437.5
