The width of a rectangle is 62 units less than its length. f x is the rectangle's length then its area is

Width(w)= x-62
Length(l)= x

Area(A) of a rectangle= Length(l) * Width(w)
A= l*w
A= (x)*(x-62)
A= x² - 62x

If the length(l) equals "x" and the width(w) equals 62 less than the value of "x",  then the area is equal to the value of "x" squared minus the value of "x" multiplied by 62.

Area= x² - 62x

Does this make sense to you? please let me know if it does not in the comments down below! Have a great day!!!
