Common core geometry unit 1 lesson 2 homework answers
Question:
What is expressed in square units?
Answer:
The area of a figure is the sum of all the square units that can be contained by that figure. Its area is the total square footage of its flat surface. It is measured in square inches, square feet, square yards, etc. When working with a square sheet, counting the number of full unit squares inside the figure gives us the area of the surface encompassed. The area is expressed in centimetres squared. Common closed plane figures include rectangles, squares, triangles, and circles.
