Ah.
.
Perimeter of a rectangle...
.
given the area.
.
So, we start with formulas and end with formulas.
.
Not necessarily, but yes, we do start with formulas, and even though you and I hate formulas, we have to use them!!
.
So, what's the area formula for the area of a rectangle?
.
Yep, b x h.
.
So? We have b x h = 32.
.
The perimeter formula is...
.
(2b) + (2h) = P, where P stands for perimeter.
.
It's obvious!!
.
We want either LEAST height and GREATEST base, or LEAST base or GREATEST height!
.
So, we'll just take base 1 and height 32.
.
You can go vice versa, too.
.
So... plug em' in!!
.
(1 x 2) + (32 x 2) = P.
.
P = 66.
.
Hope I helped!!
