rectangle with a area of A and the length is m times longer than the width what is the width and length

w width
L length
m factor
A area
-
L=mw, from description.
KNOWN: m, A.
Find w and L.

wL=A
w%28mw%29=A
mw%5E2=A
w%5E2=A%2Fm
highlight%28w=sqrt%28A%2Fm%29%29 and you can rationalize the denominator if wanted.

highlight%28L=m%2Asqrt%28A%2Fm%29%29.
