Question

Il perimetro di un rettangolo è 126 cm. La base è i tre quarti dell'altezza. Mi potreste dire come procedere? ​

Answer 1

w = 36 cm

L = 27 cm

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)

`126=2(((3)/(4) w)+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
