Pls help me with these problem solving sums
-----------------------------------------
1)You are building a rectangular brick patio surrounded by crushed stone in a rectangular courtyard.The crushed stone border has a uniform width x (in feet) you have enough money in your budget to purchase patio bricks to cover 140 sq.feet solve the equation 140=(20-2x)(16-2x) to find the width of the border
2) The distance d (in feet) that it takes a car to come to a complete stop on dry asphalt can be modeled by d=0.05+1.1s where s is the speed of the car (in miles per hour).A car has 78 feet to come to a complete stop. Find the max. Speed at which the car can travel
