Area

The video tutorial explains the concept of area and its impact on costs, particularly in the context of lawns. It demonstrates how to calculate the area of simple shapes like squares and rectangles using grids and formulas. The tutorial also covers more complex figures and provides practical examples of real-world area calculations. Advanced techniques for finding area without grids are also discussed.

Why is the cost of cutting the grass different for the two lawns?

• Because the lawns have different perimeters.

• Because the lawns have different areas.

• Because the lawns are located in different places.

• Because the lawns are made of different materials.

How can you find the area of a square using grids?

• By adding the length and breadth.

• By multiplying the length of one side by itself.

• By counting the number of circles.

• By dividing the perimeter by four.

What is the formula for finding the area of a rectangle?

• Length plus breadth

• Length times breadth

• Length divided by breadth

• Length minus breadth

How do you handle half-filled squares when calculating the area of a complex shape?

• Combine two half-filled squares to make one full square.

• Count them as half a square.

• Count them as full squares.

• Ignore them completely.

What is the first step in finding the area of a complex shape using grids?

• Count the number of fully-filled squares.

• Count the number of half-filled squares.

• Estimate the total area.

• Measure the perimeter.

How do you find the length of a rectangular window frame if you know the area and breadth?

• Divide the area by the breadth.

• Multiply the area by the breadth.

• Add the area and the breadth.

• Subtract the breadth from the area.

How can you find the area of a shape by splitting it?

• By measuring its perimeter.

• By cutting it into triangles.

• By splitting it into simpler shapes like rectangles and squares.

• By dividing it into circles.
