4.2 ft = 525 meters.... So 1 ft = 525÷42=125 meters
To get whether they are equal you have to cross multiply the numbers 18x16 and 48x3
48x3= 144
16x18= 288
144 is not equal to 288.
Therefore the rates aren’t equivalent.
It is not because it doesn’t have a length of 90 which is a right triangle
hope this helps
stay safe
brainliest is appreciated, I only need 2 more to level up :))))
