He does not need to run the buoys along the edge of the beach, so he only needs to make three sides of a rectangle in the water. Find the maximum possible swimming area AND the possible dimensions that produce the maximum area.

Suppose you use exactly 222 feet of wire fencing to enclose a rectangular grazing area for your goats. If the grazing area is half as long as it is wide, find its dimensions. Length: Width: FINISH

As an art student, Joseph has a model of a rectangular prism sculpture, which is shown below. He wants to triple the length while keeping the other dimensions the same. How will the surface area of the larger prism compare to the original one? 5 cm 2 cm 0 2019 Glynlyon, Inc. O The surface area will triple the model rectangular prism.
