What is the area of a rectangle that is 4 units long and 3 units wide?

• 7 square units

• 12 square units

• 15 square units

• 24 square units

Answer explanation

The area of a rectangle is calculated by multiplying its length by its width. Here, the length is 4 units and the width is 3 units. Thus, the area is 4 x 3 = 12 square units, making the correct answer 12 square units.

A rectangle is covered with unit squares. If the rectangle is 5 units long and 2 units wide, how many unit squares are used to cover it?

• 7 unit squares

• 10 unit squares

• 12 unit squares

• 15 unit squares

Answer explanation

To find the number of unit squares covering the rectangle, multiply its length by its width: 5 units (length) x 2 units (width) = 10 unit squares. Therefore, the correct answer is 10 unit squares.

Find the area of a rectangle with side lengths of 6 units and 2 units using the multiplication formula.

• 8 square units

• 10 square units

• 12 square units

• 14 square units

Answer explanation

To find the area of a rectangle, use the formula: Area = length × width. Here, Area = 6 units × 2 units = 12 square units. Thus, the correct answer is 12 square units.

A rectangle is 3 units long and 4 units wide. What is the area of the rectangle?

• 7 square units

• 10 square units

• 12 square units

• 15 square units

Answer explanation

The area of a rectangle is calculated by multiplying its length by its width. Here, the length is 3 units and the width is 4 units. Thus, the area is 3 x 4 = 12 square units, making the correct answer 12 square units.

If a rectangle is 8 units long and 3 units wide, what is its area?

• 11 square units

• 18 square units

• 24 square units

• 30 square units

Answer explanation

The area of a rectangle is calculated by multiplying its length by its width. Here, the area = 8 units (length) × 3 units (width) = 24 square units. Therefore, the correct answer is 24 square units.

How many unit squares are needed to cover a rectangle that is 7 units long and 2 units wide?

• 9 unit squares

• 12 unit squares

• 14 unit squares

• 16 unit squares

Answer explanation

To find the number of unit squares needed to cover a rectangle, multiply its length by its width. Here, 7 units long and 2 units wide gives 7 x 2 = 14 unit squares. Thus, the correct answer is 14 unit squares.

Calculate the area of a rectangle with dimensions 9 units by 1 unit.

• 8 square units

• 9 square units

• 10 square units

• 11 square units

Answer explanation

To find the area of a rectangle, multiply its length by its width. Here, the dimensions are 9 units and 1 unit. Thus, the area is 9 x 1 = 9 square units, making the correct answer 9 square units.

A rectangle is covered with unit squares. If the rectangle is 6 units long and 3 units wide, how many unit squares are used to cover it?

• 15 unit squares

• 18 unit squares

• 20 unit squares

• 24 unit squares

Answer explanation

To find the number of unit squares covering the rectangle, multiply the length by the width: 6 units (length) x 3 units (width) = 18 unit squares. Therefore, the correct answer is 18 unit squares.

What is the area of a rectangle that is 5 units long and 5 units wide?

• 20 square units

• 25 square units

• 30 square units

• 35 square units

Answer explanation

The area of a rectangle is calculated by multiplying its length by its width. Here, the length is 5 units and the width is 5 units. Thus, the area is 5 x 5 = 25 square units, making the correct answer 25 square units.

Find the area of a rectangle with side lengths of 4 units and 4 units using the multiplication formula.

• 12 square units

• 14 square units

• 16 square units

• 18 square units

Answer explanation

To find the area of a rectangle, use the formula: Area = length × width. Here, both side lengths are 4 units. Thus, Area = 4 × 4 = 16 square units. The correct answer is 16 square units.
