Algebraic Area & Perimeter

Front

What is the formula for the area of a rectangle?

Back

Area = length × width

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width)

Front

If the length of a rectangle is 5x and the width is 3x, what is the area?

Back

Area = 5x × 3x = 15x²

Front

If the length of a rectangle is 4 and the width is 6, what is the perimeter?

Back

Perimeter = 2(4 + 6) = 20

Front

What does 'simplest form' mean in algebra?

Back

Simplest form means the expression is reduced to its lowest terms.

Front

How do you combine like terms in algebra?

Back

Add or subtract the coefficients of terms with the same variable.

Front

What is the area of a rectangle with length 2x and width 4x?

Back

Area = 2x × 4x = 8x²

Front

What is the perimeter of a rectangle with length 3x and width 5?

Back

Perimeter = 2(3x + 5) = 6x + 10

Front

If a rectangle has an area of 24 square units, what could be its dimensions?

Back

Possible dimensions: 4 × 6, 3 × 8, etc.

Front

What is the relationship between area and perimeter in rectangles?

Back

Area measures the space inside, while perimeter measures the distance around.
