Find the dimenstons of the rectangle of largest area that has its base on the \( x \)-axis and its other two vertices above the \( x \)-axis and lying on the porabola. \[ y=5-x^{2} \] width height \( x \) [0/2 Points] A poster is to have an area of \( 240 \mathrm{in}^{2} \) with \( t \) inch morgins at the bottom and sices and a 2 inch margin at the top. nind the exact diniensions that will give the latgest printed area. Whith \( x \) height \( x^{\text {in }} \) Litianced leedback. Plewse tiy opain and duw a dlagraet. Keep in rind that ther area of a rectangle wath edges \( x \) and \( y \) is \( A=F y \). If \( x \) and \( y \) ate the edges of the poster, the edges of the printed area are colculus to find the edonts of the poster that maximize the aroa of the arinted material
