Perimeter and Area of Figures on the Coordinate Plane

The video tutorial covers the concepts of perimeter and area of figures on the coordinate plane. It explains how to calculate the perimeter by adding the lengths of all sides and provides formulas for finding the area of various shapes, including triangles, rectangles, parallelograms, rhombuses, and trapezoids. The tutorial includes example problems to demonstrate these calculations and emphasizes the importance of understanding these formulas for performing accurate calculations.

What is the first step in finding the perimeter of a figure on the coordinate plane?

• Find the area of the figure

• Find the lengths of each side

• Subtract the lengths of the sides

• Multiply the lengths of the sides

Which formula is used to find the area of a triangle?

• Base divided by height

• Base plus height

• 1/2 times base times height

• Base times height

In a rectangle, how are the base and height related?

• They are diagonal to each other

• They are parallel to each other

• They are equal in length

• They are perpendicular to each other

What is the formula for the area of a rhombus?

• Base times height

• 1/2 times diagonal 1 times diagonal 2

• Diagonal 1 plus diagonal 2

• Base plus height

How do you find the area of a trapezoid?

• Base 1 plus base 2 times height divided by 2

• 1/2 times base times height

• Base 1 times base 2 times height

• Base times height

In the example of the trapezoid, what is the area if base 1 is 2, base 2 is 4, and height is 3?

• 6

• 9

• 12

• 18

What is the area of a kite if diagonal 1 is 6 and diagonal 2 is 4?

• 12

• 24

• 8

• 10

How can you simplify finding the area of a triangle on a coordinate grid if the shape looks sideways?

• Turn the grid to align the base horizontally

• Use the perimeter instead

• Use the diagonal as the base

• Ignore the height

What is the base length of a triangle if it spans 7 units on the coordinate grid?

• 9

• 7

• 5

• 3

Why is it important to know the formulas for area and perimeter?

• They are not necessary for coordinate grids

• They are always provided in exams

• They are only used for triangles

• They help in performing calculations accurately
