Tolong jawab yaaaaa!

Tolong jawab yaaaaa!

A. Keliling
$BD = sqrt{ {AB }^{2} + {AD }^{2} } \ BD = sqrt{ {5}^{2} + {5}^{2} } \ BD = sqrt{ 50} \ BD = 5 sqrt{2}$
Jadi,
$Kel = 2(BD + BE) \ Kel = 2( 5 sqrt{2} + 5) \ Kel =10 sqrt{2} + 10$

B. Luas
$Luas = p times l \ Luas = BD times BE \ Luas = 5 sqrt{2} times 5 \ Luas = 25 sqrt{2}$

Sekian terima kasih 🙂
