Ivan i Ivan upravo su uselili u svoju novu sobu. Začudili su se koliko je prostrana. Ivan ti je dao upute kako ćeš otkriti površinu njihove sobe: "Neka se u trapezu
s osnovicama
i
dijagonale se sijeku u točki
, te neka su površine trokuta
i
redom jednake
i
. Površina trapeza je
puta veća od površine naše sobe." Kolika je površina Ivanove i Ivanove sobe (u
)?
Ivan and Ivan have just moved into their new room. They were amazed at how spacious it was. Ivan gave you instructions on how to find the area of their room: "Let the diagonals in the trapezoid
with bases
and
intersect at point
, and let the areas of the triangles
and
be equal to
and
, respectively. The area of the trapezoid is
times larger than the area of our room." What is the area of Ivan and Ivan's room (in
)?

Površina trapeza je $22$ puta veća od površine naše sobe."
