Calcola l'area di un rombo sapendo che il perimetro è 160 cm è la sua altezza misura 38,4 cm​

41,6 cm

Step-by-step explanation:

Formula for Perimeter of a rhombus:  P = 2L + 2H (H is the height, L the length)

Perimeter:  160 cm = 2L + 2(38,4 cm), or

160 cm + 76.8 cm + 2L, or

83.2 cm = 2L

and so the height (altezza) is H = 83.2 cm / 2 = 41,6 cm

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
