The perimeter, $P,$ of a rectangle with length l and width $w$ is given by the formula $P=2 l+2 w .$ The area, $A,$ is given by the formula $A=l w .$ In Exercises $119-120,$ use these formulas to find the perimeter and area of each rectangle. Express answers in simplified radical form. Remember that perimeter is measured in linear units, such as feet or meters, and area is measured in square units, such as square feet, $f t^{2},$ or square meters, $m^{2}$CAN'T COPY THE FIGURE

Find the consumers' surplus and the producers' surplus at the equilibrium level for the given price-demand and price-supply equations. Include a graph that identifies the consumers' surplus and the producers' surplus. Round all values to the nearest integer.p = D(x) = 52.7 - 0.03x; p = S(x) = 15 + 0.1xThe value of x at equilibrium is _____.
