Answer 1

Nilai t

t² = 20² - 12²

t² = 400 - 144

t² = 256

t = √256

t = 16 cm

Kelililing

K = 2(25 cm + 20 cm)

K = 2(45 cm)

K = 90 cm

Luas

L = ½ × 25 × 16

L = 25 × 8

L = 200 cm²

Answer 2

• Menentukan tinggi

t² = s² - a²

t² = 20² - 12²

t² = ( 20 × 20 ) - ( 12 × 12 )

t² = 400 - 144

t² = 256

t = √256

t = 16 cm

• Menentukan keliling

K = 2 ( alas jajar genjang + sisi miring )

K = 2 ( 25 + 20 )

K = 2 ( 45 )

K = 90 cm

• Menentukan Luas Jajar genjang

L = ½ × alas Jajar genjang × tinggi

L = ½ × 25 × 16

L = 16/2 × 25

L = 8 × 25

L = 200 cm²
