luas daerah yang diarsir adalah? tlgin dong, bsok dikumpul nih..

bangun 1
t² = 5² - {(26-20)/2}
t² = 5²-(6/2)
t² = 5²-3²
t² = 25-9
t² = 16
t = 4 cm

Luas bangun 1 = jss*t/2
L = (20+26)*4/2
L = 46*2
L = 92 cm²


bangun 2
t² = 13²-5²
t² = 169-25
t² = 144
t = 12 cm

Luas bangun 2
L = 2*a*t/2
L = 5*12
L = 60 cm²

Luas bangun diarsir = Luas bangun 1 + Luas bangun 2
Total luas = (92+60) cm²
Total luas = 152 cm²
