Question

In quadrilateral ABCD side AB parallel side DC,seg AE half seg DC if
length(AB)= 9 CM length (AE ) =10 cm A (quadrilateral ABCD) =115 CM square find length DC

Answer 1

Answer:

Length DC = 14 cm

Step-by-step explanation:

In quadrilateral ABCD side AB parallel side DC

AE ⊥ DC

AB = 9 cm

AE = 10 cm

Area of quadrilateral = 115 cm²

Area of Quadrilateral = (1/2)(AB + DC) * AE

=>(1/2)(9 + DC) * 10 = 115

=> 9 + DC = 23

=> DC = 14

Answer 2

AnsweL of DC=14 the explanation is given in above pic
