Question

Pake caranya ya.. ...

Answer 1

T^2 = 17^2 - (40-25)^2
t^2 = 289 - (15)^2
t^2 = 289 - 225
t = √64
t = 8 cm

L = 1/2 × (a+b) × t
L = 1/2 × (25+40) × 8
L = 1/2 × 65 × 8
L = 260 cm2

Jawaban: A

Answer 2

Alas segitiga = 40 - 25 = 15 cm
tinggi trapesium = √17² - 15² = 8 cm

L = 0,5 x (a+b) x t
L = 0,5 x (25+40) x 8
L = 4 x 65
L = 260 cm² (A)
