Front

What is a rectangle?

Back

A rectangle is a shape with four sides and four right angles. Opposite sides are equal in length.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 × (Length + Width)

Front

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

Back

Perimeter = 2 × (10 cm + 5 cm) = 30 cm.

Front

What is the formula for the area of a rectangle?

Back

Area = Length × Width

Front

If a rectangle has a length of 6 m and a width of 4 m, what is its area?

Back

Area = 6 m × 4 m = 24 square meters.

Front

What is a missing side length problem?

Back

A missing side length problem involves finding the length of one side of a rectangle when given the perimeter or area.

Front

If the perimeter of a rectangle is 20 cm and the length is 7 cm, what is the width?

Back

Width = (Perimeter/2) - Length = (20 cm/2) - 7 cm = 3 cm.

Front

What is the relationship between the perimeter and the side lengths of a rectangle?

Back

The perimeter is the total distance around the rectangle, calculated by adding the lengths of all sides.

Front

If a rectangle has a perimeter of 34 m and a width of 10 m, what is the length?

Back

Length = (Perimeter/2) - Width = (34 m/2) - 10 m = 7 m.

Front

What does it mean if a rectangle has equal side lengths?

Back

If a rectangle has equal side lengths, it is a square.
