 This blog is for Miss Jovanovich's algebra and geometry classes to share ideas, ask questions, and reflect on what skills and topics we are studying. If we are lucky, we might even get a chance to connect with other students studying the same stuff.

Area Formulas

Hello everyone! Hope you've had yet another fantastic week!

Today I counted the days left in my school year. There are 30 days including weekends! I am so excited for summer. As much as I have enjoyed my freshman year, I could use a break. Do you have any exciting summer plans?

On Thursday we took a test in geometry class on the areas of shapes. Below I have listed the formulas for finding the areas of different shapes:

1. Area of a Parallelogram = base * height

2. Area of a Regular Polygon = 0.5 * apothem * perimeter

3. Area of a Triangle = 0.5 * base * height

4. Area of a Trapezoid = 0.5 * (base 1 + base 2) * height

5. Area of a Rhombus/Kite = 0.5 * diagonal 1 * diagonal 2

My favorite area formula is for the area of a parallelogram, because it is so easy to remember. What is your favorite?

Well, so long for now! Good luck in the week ahead of you!
