Question

obilicz pole trójkąta a =5cm,h 1dm
a=4cm,h=25mm
a=36cm, h=5dm
a=3m,h =25dm

dajee naj i serce

Answer 1

Odpowiedź:

a) a = 5cm, h = 1dm = 10cm

P = (5 * 10) / 2

P = 50 / 2

P = 25 (cm²)

b) a = 4cm, h = 25mm = 2,5 cm

P = (4 * 2,5) / 2

P = 10 / 2

P = 5 (cm²)

c) a = 3m, h = 25dm = 2,5m

P = (3 * 2,5) / 2

P = 7,5 / 2

P = 3,75 (m²)

Liczę na naj :)
