Awoman is designing a rectangular garden that will have an area of 400 sq. ft. she needs to know how much fencing would be required for various dimensions of the garden. let p(w) denote the perimeter o

For this question, it is asking for the perimeter of this garden. We have already known the area of a quadrilateral is: base × height (= 400 sq.ft ) Hence, let p become the base, then the height equals to 400÷p or 400/p. Then we can state that the perimeter equals to ( base + height ) ×2， in this case, it is (p +400/p)×2 =0

Dis the answer for this question
