Answer:
(A)
Step-by-step explanation:
Given is the trapezoid which consists of two triangles and one rectangle, thus from ΔPST, we have
⇒
Now, area ΔPST=
Also, area ΔQUR=
Area rectangle PQUT=
Therefore, area trapezoid PQRS= area ΔPST+area ΔQUR+Area rectangle PQUT
=
Hence, area of trapezoid=
$40000
PRT/100
20000*8*25/100=40000
