Question

A-bok kwadratu Ob-odwód kwadratu P=a² pole kwadratu

x x 324m²

a - jeden bok prostokąta b- drugi bok prostokąta Ob P=ab
12 cm x x 96 cm²
x 11 m x 143 m²
18 dm x x 126 dm²

Answer 1

1. P = a²
a = √324m²
a = 19,0262976m
Ob = a * 4
Ob = 76,1051904

2. P = a * b
Ob = 2a + 2b

a) 96cm² : 12cm = 8cm
Ob = 12cm * 2 + 8cm * 2
Ob = 40cm

b)143m² : 11m = 13m
Ob = 11m * 2 + 13m * 2
Ob = 38m

c)126dm² : 18dm = 7dm
Ob = 18dm * 2 + 7dm * 2
Ob = 50dm
