Perimeter of Squares, Rectangles, & Triangles

Front

What is the formula for the perimeter of a square?

Back

The perimeter of a square is calculated using the formula: P = 4s, where s is the length of one side.

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated using the formula: P = 2(l + w), where l is the length and w is the width.

Front

What is the formula for the perimeter of a triangle?

Back

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

Front

If a square has a side length of 5 cm, what is its perimeter?

Back

The perimeter is 20 cm (P = 4 * 5).

Front

If a rectangle has a length of 8 cm and a width of 3 cm, what is its perimeter?

Back

The perimeter is 22 cm (P = 2(8 + 3)).

Front

In an isosceles triangle, if the two equal sides are 5 cm each and the base is 4 cm, what is the perimeter?

Back

The perimeter is 14 cm (P = 5 + 5 + 4).

Front

What is the distance around an object called?

Back

The distance around an object is called the perimeter.

Front

If the perimeter of a triangle is 30 cm and two sides are 10 cm each, what is the length of the third side?

Back

The length of the third side is 10 cm (30 - 10 - 10 = 10).

Front

What is the perimeter of a triangle with sides measuring 6 cm, 8 cm, and 10 cm?

Back

The perimeter is 24 cm (6 + 8 + 10).

Front

If a rectangle has a perimeter of 30 cm and one side is 10 cm, what is the length of the other side?

Back

The length of the other side is 5 cm (P = 2(l + w) => 30 = 2(10 + w) => w = 5).
