Area and Perimeter Practice

Front

What is the formula for the perimeter of a rectangle?

Back

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

Front

What is the formula for the area of a rectangle?

Back

The area (A) of a rectangle is calculated using the formula: A = b ⋅ h, where b is the base (length) and h is the height (width).

Front

What is the formula for the area of a triangle?

Back

The area (A) of a triangle is calculated using the formula: A = \frac{1}{2} b ⋅ h, where b is the base and h is the height.

Front

What units are used to measure area?

Back

Area is measured in square units, such as square centimeters (cm²), square meters (m²), or square inches (in²).

Front

What is the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of all three sides.

Front

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

Back

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

Front

If a rectangle has a length of 8 cm and a width of 4 cm, what is its area?

Back

The area is A = 8 cm ⋅ 4 cm = 32 cm².

Front

If a triangle has a base of 6 cm and a height of 4 cm, what is its area?

Back

The area is A = \frac{1}{2} (6 cm ⋅ 4 cm) = 12 cm².

Front

What is the perimeter of a rectangle with a length of 12 cm and a width of 3 cm?

Back

The perimeter is P = 2(12 cm + 3 cm) = 30 cm.

Front

What is the area of a square with a side length of 5 cm?

Back

The area is A = 5 cm ⋅ 5 cm = 25 cm².
