Mohon bantuannya dari no 26 samapi 28 dan jalannya yaaa

Bangun Datar

26. Jajar Genjang ABCD
AB= CD = 11
BC = AD = 25
Luas ABCD = 264
L = alas x tinggi
264 = AB x BF
BF = 264/AB = 264/11 = 24
ΔBFC siku siku di F
FC² = BC² -BF² = (25²) -(24)² = 49
FC = 7
DF+FC = DC
DF = DC - FC
DF = 11 - 7 = 4
BE= DF =  4 cm

27. Segitga PQR
PT tegak lurus QR
QS tegak lurus PR
PT x QR = QS x PR
PT x20 = 16 x 15
PT = 16 x 15 / (20)
PT = 12 cm
ΔPTR siku siku di T
TR² = PR² - PT²
TR² = 15² - 12² = 81
TR = 9
TR + QT = QR
9 + QT = 20
QT = 20 - 9
QT = 11 cm

28. Trapesium ABCD
Luas = 168
CD = 15
AB = 27
tinggi = CE = DF
Luas = 1/2 (CD+AB)(CE)
168 = 1/2 (15+27)(CE)
CE = 168/21 = 8

DF = EB = 1/2 (AB- CD)
DF= EB = 1/2 (27-15) = 6

ΔBEC siku siku di E
BC² = EB²+ CE²
BC² = 6² +8² = 100
BC = 10
AD = BC = 10 cm
