PQ = 16 cm
QS = 8 cm
SP = √(PQ² - QS²)
SP = √(16² - 8²)
SP = √256 - 64 = 8√3
segitiga RSP sebanding dengan segitiga PSQ.
SR/SP = SP/SQ
SR/8√3 = 8√3/8
SR = 24 cm (C)
13. PS = 12 cm
SR = 8 cm
segitiga RSP sebanding dengan segitiga PSQ
SQ/PS = PS/RS
SQ/12 = 12/8
SQ = 12 . 12/8
SQ = 18 cm
RQ = SR + SQ = 8 + 18 = 26 cm
luas PQR = 1/2 . RQ . PS
= 1/2 . 26 . 12
= 156 cm² (B)
