Question

teorema de Pitágoras

Answer 1

Boa noite 

2)

(6√2)² = x² + x²
72 = 2x²
x² = 72/2 = 36

a) x = 6 

b)

BC = x = 6
BE = 2x = 12

Area BCDE A  = 6*12 = 72 u,a


3)

a² = 2² + 4² = 4 + 16 = 20
a = 2√5

b² = 4² + 8² = 16 + 64 = 80
b = 4√5

c² = a² + b² = 20 + 80 = 100
c = 10

a) a = 2√5
b) b = 4√5
c) c = 10
d) MNPQ = 4 + 4 + 8 + 10 + 2 = 28
