Algebra Tiles Area and Perimeter

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width)

Front

If x = 3, what is the perimeter of a rectangle with length x + 2 and width x + 1?

Back

Perimeter = 20 units

Front

What is the formula for the area of a rectangle?

Back

Area = length × width

Front

If x = 3, what is the area of a rectangle with length x + 2 and width x + 1?

Back

Area = 25 un²

Front

What does 'un' stand for in area measurements?

Back

'un' stands for units, which is a measure of area.

Front

What is the expression for the perimeter of a shape with sides 2x, 2x, 2, and 2?

Back

Perimeter = 4x + 4

Front

What is the expression for the area of a rectangle with length x and width x + 2?

Back

Area = x(x + 2) = x² + 2x

Front

If the area of a rectangle is given by the expression x² + 2x + 2, what are the dimensions?

Back

Dimensions cannot be determined without specific values for x.

Front

What is the relationship between area and perimeter in geometric shapes?

Back

Area measures the space inside a shape, while perimeter measures the distance around it.

Front

If the perimeter of a rectangle is 2x + 8, what can you say about its dimensions?

Back

The dimensions can be expressed in terms of x, but specific values are needed for length and width.
