Final answer:
Since Chad's backyard dimensions are not provided, we cannot calculate the exact area he needs to cover with grass. The area is generally found by multiplying the length by the width of the backyard. Examples related to measurements help demonstrate how to use dimensions to calculate or estimate area.
Step-by-step explanation:
To determine how much area Chad needs to cover with grass, we need to calculate the area of his backyard using the dimensions he measured. Unfortunately, the dimensions were not provided in the question, so we cannot calculate the exact area. However, to calculate the area of a rectangular plot of land like a backyard, you would multiply the length by the width, which gives you the measurement in square feet or square meters, depending on the units used.
If we take some of the provided information and examples related to measurements and calculations, we can understand how to approach the problem. For instance, Rano has a rectangular backyard with dimensions of 50 feet by 30 feet would have an area of 50 x 30 = 1500 square feet. Similarly, an approach to estimating area can be demonstrated through the example of estimating the area of a regulation basketball court using the size of an average male for a rough approximation.
