MATHS - Geometry - Perimeter

The video tutorial explains how three farmers, Bob, Jack, and Jill, can calculate the amount of fencing needed for their fields by understanding the concept of perimeter. It covers calculating the perimeter for simple shapes like rectangles, compound shapes, and circles, using examples from each farmer's field. The tutorial also provides examples of more complex shapes, combining different geometric figures, to demonstrate how to calculate their perimeters.

What is the perimeter of Bob's rectangular field if the sides are 80 meters and 200 meters?

• 360 meters

• 560 meters

• 480 meters

• 640 meters

How many sides does Jack's compound shape have?

• 8 sides

• 14 sides

• 10 sides

• 12 sides

What formula can be used to find the circumference of a circle?

• radius + diameter

• π radius or 2π diameter

• 2π radius + diameter

• 2π radius or π diameter

What is the perimeter of a shape that combines a rectangle and a semicircle?

• 128 meters

• 96 meters

• 64 meters

• 32.9 meters

What is the perimeter of a shape with missing dimensions of 7 meters and 8 meters?

• 15 meters

• 32.9 meters

• 64 meters

• 23 meters
