(2) PR = 13cm
To find:- PQ
Solution:-
PQ = QR ... (1) [sides of square]
In ∆PQR, ∠PQR = 90° ... [Angle of a square]
∴ PQ + QR = PR ... [Pythagoras theorem]
∴ PQ + PQ = 13 ... [From (1) and given]
∴ 2PQ = ______
∴ PQ =
169
2
∴ PQ = _______ ... [________________]
∴ PQ = 13×√2
√2×√2
∴ PQ = __________ cm.
