Finding Area and Perimeter on the Coordinate Plane

This video tutorial teaches how to find the area and perimeter of shapes on a coordinate plane. It covers calculating these measurements for rectangles and triangles, using base and height for area, and adding side lengths for perimeter. The tutorial also includes plotting points to form shapes and encourages viewers to review the material for better understanding.

How do you calculate the perimeter of a rectangle?

• Multiply base by height

• Add the length of all sides

• Divide the base by the height

• Subtract the width from the length

What is the formula for the area of a rectangle?

• Length minus width

• Length divided by width

• Length times width

• Length plus width

If a rectangle has a length of 6 units and width of 4 units, what is its area?

• 10 square units

• 24 square units

• 20 square units

• 14 square units

What is the perimeter of a rectangle with sides of 8 units and 5 units?

• 26 units

• 40 units

• 13 units

• 20 units

How do you find the area of a triangle?

• (Base times height) divided by 2

• Base plus height

• (Base plus height) divided by 2

• Base times height

A triangle has a base of 11 units and a height of 9 units. What is its area?

• 49.5 square units

• 99 square units

• 20 square units

• 90 square units

Given four points on a coordinate plane, how do you determine the shape they form?

• By calculating the distance between each point

• By plotting them and connecting in order

• By adding their values

• By multiplying their coordinates

What is the perimeter of a rectangle with sides measuring 4 units and 9 units?

• 18 units

• 36 units

• 26 units

• 13 units

If a rectangle's area is calculated as 36 square units, what could be its dimensions?

• 6 units by 6 units

• 9 units by 4 units

• 18 units by 2 units

• 12 units by 3 units

To find the area of a shape on a coordinate plane, you need to know:

• The coordinates of all vertices

• The length of the diagonal

• The measurements of the sides

• The color of the shape
