plzz help in maths..

Answer 1

hi mate here is the answer

const two parallelograms on the same base and between same parallels

name one parallelogram ABCD and the other EBCF

in triangle ABE and triangle DCE,

AB=DC

angle A = angle D

angle E= angle F

.: triangle ABE is congruent to triangle DCF by AAS congruency

conguent fig are equal in area

.: ar(ABE) = ar(DCF)----------------- eq 1

add the first eq to ar(BEDC)

ar(ABE) + ar(BEDC) = ar (DCF) + ar(BEDC)

.: ar(ABCD) = ar(EBCD)

hope it is helpful
