h = √f²+g²
f=8
g=b-a
g=12-6
g=6
h = √8²+6²
h = √64+36
h = √100
h=10
P = [(a+b) x h] : 2
P = [(12 + 6)] x 10] :2
P = (18x10) : 2
P = 180 : 2
P = 90cm²
p=1/2*6* (6+12)
P=3*18
P=54 cm2
a²+b²=c²
a=6cm
b=?
c=8cm
6²+b²=8²
36+b²=64
b²=64-36
b²=28 /√
b=√28= 4√7
P=(a+b)*h/2
P=(6+12)*4√7/2
P=18*4√7/2
P=36√7 cm²
