Question

va rog sa ma ajutati cu aceasta problema la matematica am mare nevoie va rooooggggggg.​

Answer 1

Răspuns:

a) R= 8

R= l₄√2/2⇒ l₄= 16/√2=16√2/2=8√2 cm

a₄= l₄/2=8√2/2=4√2 cm

S₄= l₄²= (8√2)²=128 cm²

b) l₄= 6√2

R= 6√2·√2/2= 6 cm

a₄= 6√2/2=3√2 cm

S₄=(6√2)²=72 cm²

c) a₄=5

a₄= l₄/2⇒ l₄ =5·2=10 cm

R= 10√2/2=5√2 cm

S₄= 10²=100 cm²

d) S₄= 16 cm²= l₄²

l₄=√16= 4 cm

R= 4√2/2=2√2 cm

a₄= 4/2=2 cm
