GED Math Geometry: Area and Perimeter of Squares, Rectangles, Triangles, Parallelograms, Trapezoids

Описание: In this video, you'll learn how to ace questions on area and perimeter for the GED test math section!

Perimeter Formulas:

Perimeter of square = 4 x side

Perimeter of rectangle = 2 x length + 2 x width

Perimeter of triangle = side a + side b + side c

Formulas for area:

Area of square = side^2

Area of rectangle = length x width

Area of triangle = (1/2) x base x height

Area of parallelogram = base x height

Area of trapezoid = (1/2) x height (base a + base b)

***Note: You don't have to memorize these formulas for your test, you just have to know how to use them. That being said, I recommend trying to memorize the formulas for squares, rectangles, and triangles, because this will save you time on the test!
