4.

a)

h² + 2² = 3²

h² + 4 = 9

h² = 9 - 4

h² = 5

h = √5

P = a · h

a = 2 + 5 = 7

P = 7 · √5

P = 7√5

b)

h² + 3² = 4²

h² + 9 = 16

h² = 16 - 9

h² = 7

h = √7

P = a · h

a = 3 + 4 = 7

P = 7 · √7

P = 7√7

5.

a)

a² + 6² = 10²

a² + 36 = 100

a² = 100 - 36

a² = 64

a = √64

a = 8

P = a · b

P = 8 · 6 = 48

b)

a² = 5² + 5²

a² = 25 + 25

a² = 50

a = √50 = √(25 · 2)

a = 5√2

h = 5

P = a · h

P = 5√2 · 5 = 25√2
