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

what's the trouble? They actually give you the equations to solve. What do you get for answers?
1) The border is 3 Feet
lalalala
