Perimeter of Rectangles

Front

What is the formula for calculating the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is calculated using the formula P = 2(length + width).

Front

If a rectangle has a length of 10 cm and a width of 5 cm, what is its perimeter?

Back

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

Front

What is the perimeter of a square with a side length of 6 m?

Back

The perimeter of the square is 24 m, calculated as P = 4 * side length = 4 * 6 m.

Front

How does the perimeter of a rectangle change if both the length and width are doubled?

Back

If both the length and width are doubled, the perimeter also doubles.

Front

What is the perimeter of a rectangle with a length of 12 in and a width of 8 in?

Back

The perimeter is 40 in, calculated as P = 2(12 in + 8 in).

Front

If the perimeter of a rectangle is 50 cm and the length is 15 cm, what is the width?

Back

The width is 10 cm, calculated using the formula P = 2(length + width).

Front

What is the relationship between the perimeter and area of a rectangle?

Back

The perimeter is the total distance around the rectangle, while the area is the space contained within it; they are related but measure different properties.

Front

What units are used to measure perimeter?

Back

Perimeter is measured in linear units such as centimeters (cm), meters (m), inches (in), or feet (ft).

Front

If a rectangle has a perimeter of 60 m and a width of 15 m, what is the length?

Back

The length is 15 m, calculated using the formula P = 2(length + width).

Front

What is the perimeter of a rectangle with equal sides?

Back

If a rectangle has equal sides, it is a square, and the perimeter is calculated as P = 4 * side length.
