Trapezoid - hard example

Base of the trapezoid are: 24, 16 cm.
Diagonal 22, 26 cm.
Calculate its area and perimeter.

Result

S =  264 cm2
o =  0 cm

Solution:

S=((24+16+22+26)/2) (((24+16+22+26)/2)2416) (((24+16+22+26)/2)22) (((24+16+22+26)/2)26)=264 cm2S=\sqrt{ ((24+16+22+26)/2) \cdot \ (((24+16+22+26)/2)-24-16) \cdot \ (((24+16+22+26)/2)-22) \cdot \ (((24+16+22+26)/2)-26) } = 264 \ cm^2
