A composite figure is formed by combining a square and a triangle. Its total area is 50.5 ft2. The area of the triangle is 25.5 ft2. What is the length of each side of the square? Complete the explanation. The area of the square isft2, so each side of the square isft.

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

d will be the best answer
