Question

Please Help!
Given rectangle PQRS with PQ=QR, PQ=SP, and SQ=5√2. Find RQ.
a) not enough info.
b) √2
c) 5
d) 5√2

Answer 1

Ive concluded that is isnt either A or D. So it has to be B or C?

Answer 2

A rectangle having 2 adjacent sides equal, is a square.
now, since it is a square, and the diagonal is 5(2)^1/2,
the side of the square is 5.

Answer 3

so 5^2+ 5 sqrt 2^2 ??

Answer 4

Nvm, Its C, right?

Answer 5

\[a ^{2}+a ^{2}=({5\sqrt{2}})^{2}\]
hence, a=5.
C is the correct answer.
