Oblicz pole figury o wymiarach podanych na rysunku.

a) P=10*5/2
P=50/2
P=25
b) P=(2+4,5)*8/2
P=6,5*4=26
[tex]a)\\a = 5\\h = 12\\\\P = \frac{1}{2}ah\\\\P = \frac{1}{2}\cdot5\cdot10 = 25 \ \ [j^{2}][/tex]
[tex]b)\\a = 4\frac{1}{2} = 4,5\\b = 2\\h =8\\\\P = \frac{a+b}{2}\cdot h\\\\P = \frac{4,5+2}{2}\cdot8 =6,5\cdot4 = 26 \ \ [j^{2}][/tex]
