Hitunglah luas jajargenjang di bawah ini !
- alas
[tex]22 - \sqrt{ {26}^{2} - 24 } [/tex]
[tex] = 22 - \sqrt{676 - 576} [/tex]
[tex] = 22 - \sqrt{100} [/tex]
= 22 - 10 cm
= 12 cm
- Luas
= a × t
= 12 cm × 24 cm
= 288 cm²
[tex] \pink{\boxed{\red{\boxed{\purple{\mathfrak{\ast ~ \blue{Celia ~ Claire} ~ \ast}}}}}}[/tex]
Jawaban:
Alas
22 - √26² - 24²
= 22 - √(26 × 26 ) - ( 24 × 24 )
= 22 - √676 - 576
= 22 - √100
= 22 - 10
= 12 Cm
Luas
L = a × t
L = 12 × 24
L = 288 Cm²
