Perimeter on coordinate plane

Front

What is the formula to calculate the distance between two points (x1, y1) and (x2, y2) on a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

How do you find the midpoint between two points (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

What is the perimeter of a polygon?

Back

The perimeter is the total distance around the polygon, calculated by adding the lengths of all its sides.

Front

If a rectangle has a length of 5 units and a width of 3 units, what is its perimeter?

Back

Perimeter = 2(length + width) = 2(5 + 3) = 16 units.

Front

What is the distance between the points (1, 2) and (4, 6)?

Back

Distance = √((4 - 1)² + (6 - 2)²) = √(9 + 16) = √25 = 5.

Front

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

Back

Perimeter = 3 + 4 + 5 = 12 units.

Front

How do you calculate the perimeter of a polygon with vertices at (1,1), (1,4), (4,4), and (4,1)?

Back

Perimeter = 3 + 3 + 3 + 3 = 12 units.

Front

What is the distance between the points (-4, 5) and (7, 18)?

Back

Distance = √((7 - (-4))² + (18 - 5)²) = √(121 + 169) = √290 ≈ 17.03.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width)
