Question

Pake cara nya ya! tolong di jawab

Answer 1

Pake rumus pythagoras
 bentar saya kasih jawabannya
nih:
OQ²=PQ²-PO²
OQ²=41²-40²
OQ²=1681-1600
OQ=√81
OQ=9

SR²=SO²+OR²
SR²=9²+12²
SR²=81+144
SR=√225
SR=15

D1=POR=52
D2=SOQ=18

JADI :
K=PS+SR+RQ+QP
K=41+15+15+41
K=112

L=1/2*D1*D2
L=1/2*52*18
L=468
GITU

Answer 2

PO = 40
PQ = 41
OR = 12

OQ² = PQ² - PO²
       = 41² - 40²
       = 1681 - 1600
OQ  = √81
       = 9

OQ = OS

SR² = OS² + OR²
       = 9² + 12²
       = 81 + 144
 SR = √225 = 15

D1 = PO + OR = 40 + 12 = 52
D2 = QO + OS = 9 + 9 =18

KELILING = PQ + QR + RS + SP = 112

LUAS = D1 X D2 X 1/2 = 468
