Answer:
4
Explanation:
EFGH is congruent with QRSP. QRSP has to go in this order because the letters were scattered around the corners. EF is the same length as QR. If EF is 4 and and E4 is the same length as QR, then QR = 4.
the length of qp should be 3
rotating the polygon shows that they are the same, the previous polygon has a he of 3 as well.
