2.6 Perimeter

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

If a triangle has sides of lengths a, b, and c, how do you calculate its perimeter?

Back

The perimeter of a triangle is calculated by adding the lengths of all its sides: P = a + b + c.

Front

What does the term 'perimeter' mean?

Back

Perimeter is the total distance around the outside of a shape.

Front

How do you find the perimeter of a polygon?

Back

To find the perimeter of a polygon, add the lengths of all its sides.

Front

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

Back

The perimeter is P = 2(3 + 5) = 16 units.

Front

If the width of a rectangle is represented as (2x + 3) and the length as (2x - 4), what is the expression for the perimeter?

Back

The perimeter is P = 2((2x + 3) + (2x - 4)) = 4x + 2.

Front

What is the perimeter of a triangle with sides 4, 5, and 6?

Back

The perimeter is P = 4 + 5 + 6 = 15.

Front

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

Back

The perimeter of a square is P = 4x.

Front

If a triangle has two sides of length x and one side of length y, what is the expression for its perimeter?

Back

The perimeter is P = x + x + y = 2x + y.

Front

What is the perimeter of a rectangle with a length of 10 and a width of 4?

Back

The perimeter is P = 2(10 + 4) = 28.
