A rectangle is required to have an area of 4 square feet but it's dimensions may vary. If one side has a length x, express the perimeter p of the rectangle as a function of x.
A rectangle is required to have an area of 4 square feet but it's dimensions may vary. If one side has a length x, express the perimeter p of the rectangle as a function of x.
I think the answer is
p = 2(2 + x)
Can someone please verify?
Let the length of the rectangle be and the width be .
Thanks for the correction. I just picked up a book and this problem was one of first exercises. The old solve equations with a few unknowns eluded me. Thank you kindly for the verification.
