#0807 Order of Operations, Perimeter, and Area💯🎺🔴

Front

What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does 'Perimeter' mean?

Back

Perimeter is the total distance around the outside of a shape. It is calculated by adding the lengths of all the sides.

Front

What is 'Area'?

Back

Area is the amount of space inside a two-dimensional shape. It is measured in square units and can be calculated using different formulas depending on the shape.

Front

Calculate the area of a rectangle with length 5 units and width 6 units.

Back

Area = length × width = 5 × 6 = 30 square units.

Front

Calculate the perimeter of a rectangle with length 5 units and width 6 units.

Back

Perimeter = 2 × (length + width) = 2 × (5 + 6) = 22 units.

Front

What is the result of 3 + 6 × 4?

Back

27 (according to the Order of Operations, multiplication is done before addition).

Front

What is the result of 4(8²)?

Back

256 (first calculate 8² = 64, then multiply by 4).

Front

What is the result of 8(6 + 4)?

Back

80 (first calculate the expression in parentheses: 6 + 4 = 10, then multiply by 8).

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height.

Front

What is the formula for the perimeter of a square?

Back

Perimeter = 4 × side length.
