A rectangular enclosure has an area in square meters given by A=-2w^2+36w, where w is the width of the rectangle in meters. What is the maximum area of the enclosure?

Answer 1

maximum area of enclosure, need to find the maximum height of the enclosure

first find the width

w= -b/2a=-36/2(-2)=9 meter

maximum area of enclosure , find A(9)

A(9)= -2(w)^2+36(w)= ? m^2
