Question

Suatu segitiga memiliki luas 60 cm² dan tingginya 8 cm. Hitunglah panjang sisinya ?

Answer 1

Luas segitiga = 1/2 * a * t
60 = 1/2 * a * 8
60 = 4a
60/4 = a
15 = a

sisi miring = 8^2+ 15^2
sisi miring = 64 + 225
sisi miring = 289
sisi miring = akar 289
>> = 17

sisi alas = 15 cm
sisi miring = 17 cm

Answer 2

L = 1/2 x a x t
60 = 1/2 x a x 8
60/4 = a
a = 15

sisi miring = √(15² + 8²)
= √(225 + 64)
= √289
= 17
Sisi = 8, 15, 17
