Area and Perimeter of a Triangle and a Rectangle

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = (base * height) / 2.

Front

What is the formula for the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of its three sides: Perimeter = side1 + side2 + side3.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is given by the formula: Area = length * width.

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter of a rectangle is given by the formula: Perimeter = 2 * (length + width).

Front

How do you convert square inches to square centimeters?

Back

To convert square inches to square centimeters, multiply the area in square inches by 6.4516.

Front

What is the area of a pizza with a radius of 3 inches?

Back

The area of a pizza is calculated using the formula: Area = π * radius². For a radius of 3 inches, Area = π * (3)² = 28.27 in² (approximately).

Front

What is the relationship between the area and perimeter of a triangle?

Back

The area and perimeter of a triangle are related but measure different properties; area measures the space inside the triangle, while perimeter measures the distance around it.

Front

What units are used to measure area?

Back

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

Front

What is the significance of the base and height in calculating the area of a triangle?

Back

The base and height are crucial for calculating the area of a triangle; the base is one side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex.

Front

How do you find the perimeter of a rectangle if you know the area?

Back

To find the perimeter of a rectangle from the area, you need to know either the length or width. Use the area formula (Area = length * width) to find the missing dimension, then apply the perimeter formula.
