The park will be W meters wide and L meters long, where the length is two times the width. The park will be enclosed by a fence on all 4 sides, with an additional segment of fence running through the middle of the park, dividing it into two square areas. If a total of 1,400 meters of fence is used to enclose the park and divide it into the two square areas as described, which of the following systems of equations could be solved to determine the width and length of the park? W = 2L 2W + 2L = 1,400 W = 2L 3W + 2L = 1,400 { w L = 2W 2W + 2L 1,400 L = 2W | 3W + 2L = 1,400
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
