a field in the shape of trapezium whose parallel sides are 25m and 10m. the non parallel sides are 14m and 13m. find the area of the field.
Name the trapeziumas A B C D where AB=10, BC=13, CD=25 and DA=14.
made an imginary line as altitude from B on CD and name it X so that angle BXC=90o.Then XC = 10 and XD = 15.
According to pythogoras theorm-
H2=P2*H2
so BC2 =XC2 *BX2
132=102 *BX
169 -100 =BX2
BX2 = 69
BX =8.30
area of trapesium = sum of ll sides * distance b/w them
= 30 *8.30
=249 mt2
