Question

Tentukan luas segitiga jika diketahui:
A.alas=8cm,tinggi=7cm
B.alas=10cm,tinggi=6cm
C.alas=6cm,tinggi=12cm

Answer 1

Luas segitiga = (alas x tinggi)/2a. L = (a x t)/2       = (8 x 7)/2       = (56)/2       = 28 cm^2
b. L = (a x t)/2       = (10 x 6)/2       = (60)/2       = 30 cm^2
c. L = (a x t)/2       = (6 x 12)/2       = (72)/2       = 36 cm^2

Answer 2

A.1/2 8×7=28 cm2
B.1/2 10×6=30 cm2
C.1/2 6×12=16 cm2
