tinggi= a²+b²=c² ⇒ 5²+b²=15² ⇒ 25+ ... = 225 ⇔ b²= 225-25=200 ⇔ √200= 14,14 = 14
Luas= a×t= 7×14= 98
19) Luas trapesium= 1/2 (a+b)×t
tinggi= a²+b²=c² ⇒ 7²+b²=25² ⇒ 49+ ... = 625 ⇔ b²= 625-49= 576 ⇔√576= 24
Luas= 1/2 (24+10)×24 = 1/2×34×24 =408
7) luas bangun 1= s×s= 10×10= 100
luas bangun 2= 1/2×a×t = 1/2×10×(34-10) = 1/2×10×24 = 10×12= 120
jumlah luas kedua bangun 100+120 = 220 ×45.000= Rp 9.900.000,00
