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
- 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
