4.6 - GR2.1 - Question 2

Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is the total distance around the rectangle, calculated by adding the lengths of all four sides. For a rectangle, it can be calculated using the formula: P = 2(length + width).

Front

What is the area of a rectangle?

Back

The area of a rectangle is the amount of space inside the rectangle, calculated by multiplying the length by the width. The formula is: A = length × width.

Front

If a rectangle has a length of 15 feet and a width of 10 feet, what is its perimeter?

Back

The perimeter is 50 feet, calculated as P = 2(15 + 10) = 50.

Front

If a rectangle has a length of 15 feet and a width of 10 feet, what is its area?

Back

The area is 150 square feet, calculated as A = 15 × 10 = 150.

Front

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

Back

The formula is P = 2(length + width).

Front

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

Back

The formula is A = length × width.

Front

What units are used to measure area?

Back

Area is measured in square units, such as square feet (ft²), square meters (m²), etc.

Front

What units are used to measure perimeter?

Back

Perimeter is measured in linear units, such as feet (ft), meters (m), etc.

Front

If the length of a rectangle is doubled, how does that affect the perimeter?

Back

If the length is doubled, the perimeter also increases, calculated as P = 2(new length + width).

Front

If the width of a rectangle is halved, how does that affect the area?

Back

If the width is halved, the area decreases, calculated as A = length × (new width).
