As per the statement:
the length of a rectangle is four times its width.
⇒
It is also given that: area of rectangle is 1024 cm square
Substitute the given values in [1] we have;
⇒
Divide both sides by 4 we have;
or
Taking square root both sides we have;
cm
Therefore, the width of the rectangle is, 16 cm
It would prolly be (b=-1.6).
