Algebra Tiles Area and 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 is 3x and the width is 2, what is the area?

Back

Area = 3x × 2 = 6x

Front

If the length is 4 and the width is 5, what is the perimeter?

Back

Perimeter = 2(4 + 5) = 18

Front

What does 'x' represent in algebra tiles?

Back

'x' represents a variable that can take different values.

Front

If x = 3, what is the area of the algebra tile represented by 3x + 1?

Back

Area = 3(3) + 1 = 10 units²

Front

If x = 3, what is the perimeter of the algebra tile represented by 2x + 8?

Back

Perimeter = 2(3) + 8 = 14 units

Front

What is the area of a square with side length x?

Back

Area = x²

Front

What is the perimeter of a square with side length x?

Back

Perimeter = 4x
