Il perimetro di un rettangolo è 126 cm. La base è i tre quarti dell'altezza. Mi potreste dire come procedere?
1 answer:
Answer:
w = 36 cm
L = 27 cm
Step-by-step explanation:
I am translating and I see that perimeter of rectangle is 126 cm and the base (assuming Length) is (3/4) the height.
P = 2(l+w)
Divide both sides by 2, so you get
(3/4)w+(4/4)w=(126/2)
(7w/4)=63
Multiply both sides by 4,
7w=252, then divide both side by 7,
w = 36, Width is 36 cm, so Length is (3/4), which is L = 27 cm

Hi there!
Use the Pythagorean theorem to find the length of the line.
If we draw an imaginary right triangle using the given line as the hypotenuse, we can derive a height of 6 units and a length of 10 units.
Use the Pythagorean theorem equation:
c² = a² + b²
Plug in the height and length:
c² = 6² + 10²
Simplify:
c² = 36 + 100
c² = 136
Take the square root of both sides:
c = √136. The correct answer is D.
