Linda made a scale drawing of her classroom for her math project. She used a scale of 1 cm = 2.5 ft. If the length of her classroom on the drawing measured 20 cm, what is the actual length of her classroom?

I dont know

Step-by-step explanation:

ty for the points tho :)

Step-by-step explanation:

1cm=2.5ft

20cm=20×2.5=50ft

50ft is the actual length of her classroom.

yeah and the opposite of cheating is studying ( you should try it some time)

step-by-step explanation:

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
