If floor of a square office is 256 square units what is the perimeter

If the area of the square is equal to 256 centimetres squared, then each side of the square would be sqrt(256) = 16.

Therefore, given that a square has four sides of equal length, the perimeter of the square would be 16 x 4 = 64 centimetres.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

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
