Penjelasan dengan langkah-langkah:
AC = BD
(5x+10)=(7x-10)
(5x-7x)=-10-10
(-2x)=-20
(x)=-20/-2
(x)=10
AC = 5(10)+10
= 50+10
= 60
BD = 7x-10
= 7(10)-10
= 70-10
s√(2) = Diagonal
s√(2) = 60
s = 60/√(2)
s = 60/√(2)x√(2)/√(2)
s = 60√(2)/2
s = 30√(2)
D =√(30)√(2)² + (30√(2)²
= √(900.2)+(900.2)
= √(1800)+(1800)
= √(3600)
= 60 cm
Luas = SXS
30√(2) x 30√(2)
900.2
1800 cm²
