Afarmer wants to build a pen for his sheep. one side of the pen will be a river. the sheep need about 2000 m2 of area to graze. about what length (x) and width (y) should the organization use to use the least amount of fencing possible?
a) length = 43 m, width = 46 m
b) length = 50 m, width = 40 m
c) length = 63 m, width = 32 m
d) length = 100 m, width = 20 m

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
