Unit 8 Flashcard Review

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is given by the formula P = 2(length + width).

Front

Calculate the perimeter of a rectangle with width (2x + 3) and length (2x - 4).

Back

P = 2((2x + 3) + (2x - 4)) = 2(4x - 1) = 8x - 2.

Front

What is the formula for the perimeter of a polygon?

Back

The perimeter of a polygon is the sum of the lengths of all its sides.

Front

What does the term 'distance' refer to in geometry?

Back

Distance refers to the length of the shortest path between two points.

Front

If the distance between points A and B is 8, what does this mean?

Back

It means that the straight line connecting points A and B measures 8 units.

Front

What is the perimeter of a figure with sides measuring 2, 2.5, 3, and 3.3?

Back

P = 2 + 2.5 + 3 + 3.3 = 10.8.

Front

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

Back

P = 2(5 + 3) = 2(8) = 16.

Front

What is the formula for the perimeter of a triangle?

Back

The perimeter (P) of a triangle is given by P = side1 + side2 + side3.

Front

Calculate the perimeter of a triangle with sides measuring 3, 4, and 5 units.

Back

P = 3 + 4 + 5 = 12 units.

Front

What is the formula for the perimeter of a square?

Back

The perimeter (P) of a square is given by P = 4 × side.
