4) Pictured below is a flowerbed that is 16 meters by 5 meters. You are hired to create a mulch border that is going to create a total combined area for the bed and mulch to reach 250 square meters. What should the width of the mulch border be?
5) Below is an aerial view of the new doughnut shop that is opening in town. The red segments represent the footprint for the shop and outdoor seating which is 117 feet (East-West) by 108 feet (North-South). The blue segments represent what is going to be dedicated to parking. If the total lot size is 242 feet (East-West) by 233 feet (North-South), what is the width of the parking lot going to be (what is the length of x)?
