QUADRATO
Formule Per Area e Perimetro:
Area=
L x L
Area=
d x d : 2
Perimetro=
L x 4
Formule Inverse:
L =
Perimetro : 4
d=
√ A x 2
L =
√ A
d² =
d x d = A x 2
RETTANGOLO:
Formule per Area e Perimetro:
Area=
b x h
Perimetro=
b + h + b + h
Formule Inverse:
b =
A : h
h =
A : b
h =
( Perimetro - b - b ) : 2
b =
( Perimetro - h - h ) : 2
PARALLELOGRAMMA:
Formule per Area e Perimetro:
Area=
b x h
Perimetro=
b1 + b2 + b1 + b2
Formule Inverse:
b1 =
A : h1
h1 =
A : b1
b1 =
( Perimetro - b2 - b2 ) : 2
b2 =
( Perimetro - b1 - b1 ) : 2
h2 =
A : b2
ROMBO:
Formule per Area e Perimetro:
Area=
D x d : 2
Area=
b x h
Perimetro =
l x 4
Formule Inverse:
D =
A x 2 : d
d =
A x 2 : D
l =
P : 4
b =
A : h
TRIANGOLO:
Formule Inverse:
b1 =
Perimetro - b2 - b3
b2 =
Perimetro - b1 - b3
b3 =
Perimetro - b1 - b2
h1 =
A x 2 : b1
h2 =
A x 2 : b2
h3 =
A x 2 : b3
Formule per Area e Perimetro:
Area=
b1 x h1 : 2
Area=
b2 x h2 : 2
Area=
b3 x h3 : 2
Perimetro =
b1 + b2 + b3
TRAPEZIO:
Formule per Area e Perimetro:
Area=
( B + b ) x h : 2
Perimetro=
B + b + l1 + l2
Formule Inverse:
B =
( B + b ) - b
b =
( B + b ) - B
h =
A : ( b + B ) x 2
( B + b ) =
A : h x 2
l2 =
( Perimetro - B - b - l1 )
l1 =
( Perimetro - B - b - l2 )
Perimetro=
B + b + l1 + l2
