Wednesday 12/18: Area Flashcard

Front

What is the formula to calculate the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = Length × Width.

Front

If a rectangle has a length of 6 ft and a width of 8 ft, what is its area?

Back

The area is 48 ft² (6 ft × 8 ft = 48 ft²).

Front

What is the combined area of two rectangles with areas of 20 cm² and 16 cm²?

Back

The combined area is 36 cm² (20 cm² + 16 cm² = 36 cm²).

Front

How do you find the area of a rectangle if you know the length and width?

Back

Multiply the length by the width.

Front

What is the area of a rectangle with a length of 12 m and a width of 8 m?

Back

The area is 96 m² (12 m × 8 m = 96 m²).

Front

What is the area of a rectangle with a length of 10 cm and a width of 6 cm?

Back

The area is 60 cm² (10 cm × 6 cm = 60 cm²).

Front

If the area of a rectangle is 72 square mm and the width is 8 mm, what is the length?

Back

The length is 9 mm (Area = Length × Width; 72 mm² = Length × 8 mm; Length = 72 mm² / 8 mm = 9 mm).

Front

What is the area of a rectangle with a length of 5 m and a width of 4 m?

Back

The area is 20 m² (5 m × 4 m = 20 m²).

Front

What does 'area' mean in geometry?

Back

Area is the amount of space inside a two-dimensional shape, measured in square units.

Front

If a rectangle has an area of 28 ft² and a width of 4 ft, what is the length?

Back

The length is 7 ft (Area = Length × Width; 28 ft² = Length × 4 ft; Length = 28 ft² / 4 ft = 7 ft).
