Question

Oblicz pole trapezu prostokątnego:

a=2pierwiastki z 3
b=4 pierwiastki z 3
h=pierwiastek z 2

Answer 1

Pt = 1/2 x (a + b) x h
Pt = 1/2 x (2√3 + 4√3) x √2
Pt = 1/2 x 6√3 x √2
Pt = 3√3 x √2
Pt = 3√6

Answer 2

P=[(a+b)*h]:2=[(2√3+4√3)*√2]:2=[6√3*√2]:2=6√6:2=3√6

Answer 3

P=1/2×(a+b)×h
P= ½×(2√3+4√3)×√2=½×6√3×√2= 3√6 / 2
