Perimeter

Front

What is the formula for calculating the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle can be calculated using the formula P = 2(length + width).

Front

If a rectangle has a length of 10 units and a width of 5 units, what is its perimeter?

Back

The perimeter is 30 units, calculated as P = 2(10 + 5) = 30.

Front

What is the perimeter of a square with a side length of 4 units?

Back

The perimeter of a square is calculated as P = 4 × side length. For a side length of 4 units, P = 4 × 4 = 16 units.

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 together.

Front

What is the perimeter of a rectangle with a length of 15 cm and a width of 10 cm?

Back

The perimeter is 50 cm, calculated as P = 2(15 + 10) = 50.

Front

If a farmer wants to build a fence around a rectangular area that is 40 feet long and 20 feet wide, how much fencing material does he need?

Back

He needs 120 feet of fencing, calculated as P = 2(40 + 20) = 120.

Front

What is the perimeter of a triangle with sides measuring 3 cm, 4 cm, and 5 cm?

Back

The perimeter is 12 cm, calculated as P = 3 + 4 + 5 = 12.

Front

What is the relationship between the sides of a rectangle and its perimeter?

Back

The perimeter of a rectangle is directly related to the lengths of its sides; it is the sum of twice the length and twice the width.

Front

How does the perimeter change if the dimensions of a rectangle are doubled?

Back

If the dimensions of a rectangle are doubled, the perimeter also doubles.

Front

What is the perimeter of a polygon with sides measuring 5 in, 10 in, 12 in, and 7 in?

Back

The perimeter is 34 in, calculated as P = 5 + 10 + 12 + 7 = 34.
