Calculate the perimeter of a rectangle with length 10 m and width 4 m.

Perimeter = 2 × (length + width) = 2 × (10 + 4) = 2 × 14 = 28 m.

The area of a square is 144 ft². What is the length of one side?

Area = side × side, so side = √(144) = 12 ft.

If the perimeter of a triangle is 30 cm and the lengths of two sides are 10 cm and 8 cm, what is the length of the third side?

Third side = 30 - (10 + 8) = 30 - 18 = 12 cm.

A rectangular field is 50 m long and 30 m wide. What is the area?

Area = length × width = 50 × 30 = 1500 m².

True or False: The perimeter of a square with a side length of 5 cm is 20 cm.

False. The perimeter is 4 × 5 = 20 cm.

Fill in the blank: The formula for the area of a rectangle is ____.

Length × width.

What is the perimeter of a square with a side length of 7 in?

Perimeter = 4 × side = 4 × 7 = 28 in.

A rectangle has a perimeter of 36 m and a length of 10 m. What is its width?

Perimeter = 2 × (length + width) → 36 = 2 × (10 + width) → 36 = 20 + 2 × width → 16 = 2 × width → width = 8 m.

A rectangular garden has an area of 120 m² and a width of 10 m. What is the length?

Area = length × width → 120 = length × 10 → length = 120 ÷ 10 = 12 m.

If a triangle has sides of lengths 5 cm, 12 cm, and 13 cm, what is its perimeter?

Perimeter = 5 + 12 + 13 = 30 cm.

True or False: The area of a circle can be calculated using the formula A = πd².

False. The area of a circle is A = πr², where r is the radius.

Calculate the area of a triangle with a base of 10 cm and a height of 6 cm.

Area = ½ × base × height = ½ × 10 × 6 = 30 cm².

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

Perimeter = 3 + 4 + 5 = 12 cm.

Fill in the blank: To find the area of a square, you multiply the ____ by itself.

Side.

A rectangular swimming pool is 25 ft long and 10 ft wide. What is the area?

Area = length × width = 25 × 10 = 250 ft².

If a square has a perimeter of 40 cm, what is the length of one side?

Perimeter = 4 × side → 40 = 4 × side → side = 40 ÷ 4 = 10 cm.

Calculate the area of a rectangle with a length of 8 m and a width of 3 m.

Area = length × width = 8 × 3 = 24 m².

True or False: The area of a rectangle can be found by adding the lengths of its sides.

False. The area is found by multiplying the length by the width.

What is the perimeter of a rectangle with dimensions 12 cm by 5 cm?

Perimeter = 2 × (12 + 5) = 2 × 17 = 34 cm.

What is the formula for the perimeter of a rectangle?

The perimeter of a rectangle can be calculated using the formula: Perimeter = 2 × length + 2 × width.

The area of a square is found by multiplying the side by itself. If a square has a side length of 5 units, what is the area?

To find the area of a square, use the formula: Area = side × side. Thus, if the side length is 5 units, the area is 5 × 5 = 25 square units.
