Blake's Area and Perimeter Practice

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width. It is measured in square units.

Front

What is the formula for calculating perimeter?

Back

The perimeter of a shape is the total distance around it. For rectangles, the formula is P = 2(length + width).

Front

What units are used to measure area?

Back

Area is measured in square units, such as square centimeters (cm²), square meters (m²), etc.

Front

What is the perimeter of a rectangle with length 10 cm and width 5 cm?

Back

The perimeter is 30 cm (P = 2(10 + 5)).

Front

If a rectangle has an area of 20 cm² and a width of 4 cm, what is its length?

Back

The length is 5 cm (Area = length × width, so length = Area / width).

Front

What is the area of a square with a side length of 6 cm?

Back

The area is 36 cm² (Area = side × side).

Front

How do you find the missing side of a shape if you know the perimeter?

Back

Subtract the sum of the known sides from the total perimeter to find the missing side.

Front

What is the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × base × height.

Front

What is the perimeter of a triangle with sides measuring 3 cm, 4 cm, and 5 cm?

Back

The perimeter is 12 cm (3 + 4 + 5).

Front

What does 'sq cm' mean?

Back

'sq cm' stands for square centimeters, a unit of area measurement.
