Use the Area Formula

The video tutorial explains the concept of area, measured in square units, and distinguishes it from perimeter, which measures the distance around a shape. It demonstrates how to calculate the area of rectangles using the formula A = L * W, with examples in centimeters and inches. The tutorial also covers finding the area of compound figures by dividing them into rectangles and summing their areas. The importance of using square units in area calculations is emphasized throughout.

What is the primary difference between area and perimeter?

• Area and perimeter both measure the distance around a shape.

• Area and perimeter both measure the space inside a shape.

• Area measures the distance around a shape, while perimeter measures the space inside it.

• Area measures the space inside a shape, while perimeter measures the distance around it.

How do you calculate the area of a rectangle?

• Subtract the width from the length.

• Divide the length by the width.

• Add the length and width.

• Multiply the length by the width.

If a rectangle has a length of 10 cm and a width of 7 cm, what is its area?

• 70 square centimeters

• 17 square centimeters

• 77 square centimeters

• 35 square centimeters

What is the area of a rectangle with a length of 12 inches and a width of 4 inches?

• 36 square inches

• 16 square inches

• 48 square inches

• 24 square inches

How can you find the area of a compound figure?

• By subtracting the area of the smallest shape from the largest.

• By dividing the total perimeter by the number of shapes.

• By adding the areas of all the shapes within the figure.

• By multiplying the areas of all the shapes within the figure.
