Takeaways

• 😀 The square's area is calculated using the formula 'side^2', and the perimeter is '4 × side'.
• 😀 A rectangle's area is found using 'length × width', and its perimeter is '2 × (length + width)'.
• 😀 For a triangle, the area formula is '1/2 × base × height', and its perimeter is the sum of all its sides.
• 😀 The trapezoid area is calculated with '1/2 × (top + bottom) × height', and its perimeter is the sum of all sides.
• 😀 The parallelogram’s area is calculated by 'base × height', and its perimeter is the sum of all sides.
• 😀 For a circle, the area is 'π × radius^2' and the perimeter (circumference) is '2 × π × radius'.
• 😀 A rhombus' area is determined using '1/2 × diagonal 1 × diagonal 2', and its perimeter is '4 × side'.
• 😀 A kite's area is calculated by '1/2 × diagonal 1 × diagonal 2', and the perimeter is the sum of all its sides.
• 😀 Always use square units (e.g., cm², m²) for area and linear units (e.g., cm, m) for perimeter calculations.
• 😀 Key shapes in geometry include square, rectangle, triangle, trapezoid, parallelogram, circle, rhombus, and kite, each with unique formulas for area and perimeter.

Q & A

What is the formula for calculating the area of a square?

The formula for calculating the area of a square is A = S², where S is the length of one side of the square.

How do you calculate the perimeter of a square?

The perimeter of a square is calculated using the formula P = 4 × S, where S is the length of one side.

What is the difference between the area and perimeter formulas for a rectangle?

For a rectangle, the area is calculated as A = length × width, while the perimeter is calculated as P = 2 × (length + width).

How do you calculate the area of a triangle?

The area of a triangle is calculated using the formula A = 1/2 × base × height.

What is the formula for the perimeter of a triangle?

The perimeter of a triangle is calculated by adding the lengths of all three sides.

How do you calculate the area of a trapezoid?

The area of a trapezoid is calculated using the formula A = 1/2 × (base1 + base2) × height, where base1 and base2 are the lengths of the two parallel sides.

What formula is used to calculate the perimeter of a trapezoid?

The perimeter of a trapezoid is calculated by adding the lengths of all four sides.

What is the formula for the area of a rhombus?

The area of a rhombus is calculated using the formula A = 1/2 × d1 × d2, where d1 and d2 are the lengths of the diagonals.

How do you calculate the perimeter of a rhombus?

The perimeter of a rhombus is calculated using the formula P = 4 × side length, since all sides are of equal length.

What is the formula for the area of a circle?

The area of a circle is calculated using the formula A = π × r², where r is the radius of the circle.
